ABCNews.com(COLORADO SPRINGS, Colo.) -- Republican nominee Donald Trump told a crowd of supporters on Friday that he has "one of the best temperaments" of any previous presidential candidate.
"I think I have the best temperament, or certainly one of the best temperaments, of anybody that’s ever run for the office of president. Ever," he told a crowd in Colorado Springs, Colo. Friday. "Because I have a winning temperament. I know how to win."
Trump's critic have repeatedly assailed his temperament in light of his controversial remarks -- with his Democratic rival, Hillary Clinton, saying at the Democratic Convention "a man you can bait with a tweet is not a man you can trust with nuclear weapons."

ABC/ Ida Mae Astute(NEW YORK) -- For decades, political conventions have marked one of the best moments to plead your case to the American electorate and generate momentum headed toward November.
In the past, most political conventions were held several weeks apart, giving each party an opportunity to push their message and candidates -- and giving pollsters enough time to adequately measure the so-called “convention bounce.”
The convention bounce is a small -- or sometimes not-so-mall -- bump in a candidate’s support after the forceful messaging and increased media attention during that party’s convention.
Here’s what to watch for in the coming days.
What We’ve Seen So Far
We haven’t seen any new polls released since the Democratic convention just Thursday, and most quality polls won’t be released for a few days. But two polls were released shortly after the Republican convention last week.
These polls showed mixed results. Donald Trump saw a 10-point bump in a CNN/ORC poll, climbing from 42 percent support to 48 percent, his highest support since last September.
On the other hand, a CBS poll out the same day showed no net bounce for Trump at all.
Still, these polls showed other good news for the Republican nominee. Hillary Clinton hit a new low in her honest and trustworthy score in the CNN poll, with almost seven in 10 Americans saying they believe she is not honest and trustworthy.
What Have We Seen in the Past?
For the last two election cycles, the conventions have given slight tweaks to the race that have propelled the candidates toward Election Day.
In 2012, Barack Obama and Mitt Romney were nearly tied, with 47 percent for Romney and 46 percent for Obama, in ABC News/Washington Post polling. But after the convention stretch ended, Obama had opened up a six-point lead, 50-44 percent.
In 2008, John McCain was able to narrow the gap. Obama lead by six points before the convention, 49 to 43 percent. But a poll after the conventions put McCain within the margin of error, 47-45 percent.
Before that, it was not uncommon for candidates to get double-digit boosts in their support after their convention, which usually stood alone, several weeks apart from the other party’s.
What Could Be Coming
It remains to be seen how much of a bump Hillary Clinton will pick up after the Democratic convention, so we’ll be watching the next round of polling to determine whether she gained ground over Trump or whether Trump has kept the race at the dead heat.
Still, the convention bounce isn’t the only thing that matters. Debates begin between Trump and Clinton in late September, and more interviews and campaign events are sure to shape the race from here.
And political journalists also look for the “October surprise” -- an unexpected event just weeks before the election that can shape the outcome.
iStock/Thinkstock(RALEIGH, N.C.) -- With just 101 days until Election Day, a federal appeals court struck down key parts of North Carolina’s controversial voter ID law, saying “we can only conclude that the North Carolina General Assembly enacted the challenged provisions of the law with discriminatory intent.”
“We cannot ignore the record evidence that, because of race, the legislature enacted one of the largest restrictions of the franchise in modern North Carolina history,” the U.S. 4th Circuit Court of Appeals said in its ruling.
“This is a big win for voting-rights advocates and a serious rebuke to the North Carolina legislature," ABC News’ Supreme Court Contributor Kate Shaw said.
The law in question, which was passed in 2013, required voters who vote in person to show an approved form of photo identification, halted some electoral procedures like same-day voter registration and pre-registration for voters who would turn 18 by Election Day, and restricted early voting.
North Carolina is a so-called “purple state,” because it does not consistently vote for either major political party, making it neither a blue state nor a red state consistently. In 2008, a majority of North Carolinians voted for Barack Obama, but in 2012 the majority voted for Mitt Romney.
“In response to claims that intentional racial discrimination animated its action, the State offered only meager justifications,” the court found.
Proponents of the law, including North Carolina Gov. Pat McCrory, say it is needed to guard against voter fraud.
Opponents, like the North Carolina State Conference of the NAACP, which was party to the court case, believe the law -- and similar laws like it -- disenfranchise certain voters, namely minorities.
“Although the new provisions target African Americans with almost surgical precision, they constitute inapt remedies for the problems assertedly justifying them and, in fact, impose cures for problems that did not exist,” the court found.
North Carolina is one of several states that have passed voter ID laws in recent years.
Dale Ho, director of the American Civil Liberties Union’s Voting Rights Project, called the ruling, “a major victory for North Carolina voters and for voting rights.”
The North Carolina governor’s office did not immediately respond to ABC News' request for comment.
However, speaking to the public radio program, Here & Now, shortly after the law passed in 2013, McCrory said: “If we're naïve enough to think that there's no voter fraud in the 10th largest state in the United States of America, then I think we've got our head in the sand.”
Republican leaders in the North Carolina legislature blasted the court's ruling Friday.
"Since today's decision by three partisan Democrats ignores legal precedent, ignores the fact that other federal courts have used North Carolina's law as a model, and ignores the fact that a majority of other states have similar protections in place, we can only wonder if the intent is to reopen the door for voter fraud, potentially allowing fellow Democrat politicians like Hillary Clinton and Roy Cooper to steal the election," North Carolina Senate Leader Phil Berger and House Speaker Tim Moore said in a joint statement, obtained by ABC affiliate WTVD-TV in Raleigh. "We will obviously be appealing this politically-motivated decision to the Supreme Court."
North Carolina State Board of Elections Executive Director Kim Westbrook Strach told WTVD-TV, "Absent alternative guidance from the courts, voters will not be asked to show photo identification this election. Early voting will run October 20 through November 5, and same-day registration will be available at early voting sites."
"Counsel for the state are reviewing options on appeal. Regardless of the outcome, our agency will continue to educate voters and prepare elections officials ahead of November," Strach added.
A federal appeals court ruled last week that Texas' strict voter ID law violates the Voting Rights Act and ordered changes before the November election.
The Rev. Dr. William J. Barber II, president of the North Carolina NAACP has, in the past, called the law a “voter suppression law.”
Barbara Kinney for Hillary for America(PHILADELPHIA) -- Democratic presidential candidate Hillary Clinton, fresh off her historic week in Philadelphia, kicked off the last 100 days of her campaign by embarking on a bus tour that will be part of a concerted effort by the Clinton campaign to court anti-Donald Trump Republican voters.
"As of tomorrow, we have 100 days to take our case to America. So what better brace to kick off this campaign than right here in in Philadelphia where it all started 240 years ago," Clinton said to a crowd of more than 5,000 people, with her running mate, Virginia Sen. Tim Kaine, by her side.
The three-day tour will traverse through Republican-leaning counties in western Pennsylvania and eastern Ohio, areas of the country that former GOP nominee Mitt Romney won in the 2012 election. Clinton's campaign sees an opportunity to tap into the discontent among some Republicans who feel uncomfortable voting for Trump.
In Philadelphia, Clinton and Kaine, who were joined by their spouses, painted Trump as an economic danger to the nation.
"We’re going to be visiting a few places where people are making things. I find it highly amusing that Donald Trump talks about 'Make America Great Again.' He doesn’t make a thing in America except bankruptcies," Clinton said.
Kaine warmed up the crowd for Clinton and attacked Trump at the same time.
"The Republican Convention was like a twisted and negative tour. It wasn't a tour of this country. It was a journey through Donald Trump's mind. And that is a very frightening place. That is a very frightening place," Kaine said.
Clinton will also make a rare appearance on Fox News this Sunday in an effort to reach disgruntled GOP voters.
In her address to the Democratic National Convention Thursday night, Clinton presented herself as a candidate of inclusion, describing herself as someone who "will be a president for Democrats, Republicans and independents."
"Whatever party you belong to, or if you belong to no party at all, if you share these beliefs, this is your campaign," Clinton said.
Clinton's selection of Kaine as her running mate could boost her appeal with moderate Republicans. In his DNC address Wednesday night, Kaine told the story of his Republican father-in-law, a former Virginia governor, who is increasingly voting for Democrats.
"He’s voting for Democrats, because any party that would nominate Donald Trump for president has moved too far away from his party of Lincoln. And I tell ya, if any of you are looking for that party of Lincoln, we’ve got a home for you right here in the Democratic Party," Kaine said.
ROBYN BECK/AFP/Getty Images(NEW YORK) -- As Chelsea Clinton spoke at the Democratic National Convention to introduce her mother, Hillary Clinton watched her daughter in admiration from backstage before stepping out to make history as the first female nominee of a major party.
She wasn’t the only one sharing an historic moment with her daughter. Supporters across the country shared photographs on Twitter of daughters, granddaughters, mothers and grandmothers watching intently.
“I want to be able to tell my daughter that she was in my arms to watch history,” said Dan Olivo of California, who watched with his 3-month-old daughter, Ava. “It was important to me that my daughter was with me for this moment. We did it together.”
Alana Mouchard watched her 93-year-old grandmother become emotional as Clinton took the stage. “This is everything to me. I can’t imagine working thanklessly for close to a century for the empowerment of women, only to see this now,” Mouchard tweeted.
iStock/Thinkstock(WASHINGTON) -- The Democratic Congressional Campaign Committee has been targeted in a cyber-attack, the committee's national press secretary Meredith Kelly said on Friday.
"The DCCC can confirm that we have been the target of a cybersecurity incident," Kelly said in a statement to ABC News.
An investigation into the attack is ongoing but investigators have said "this is similar to other recent incidents, including the DNC breach," Kelly said, referring to the recent hack of the Democratic National Committee.
The DCCC is the main fundraising organization for Democrats running for election in the House of Representatives.
ABC News(PHILADELPHIA) -- Hillary Clinton has accepted the Democratic party's presidential nomination Thursday night in Philadelphia, making history as the first woman to be chosen to run for the highest office in the land by a major party in the United States.
"Today, we've reached a milestone in our nation's march toward a more perfect union: The first time that a major party has nominated a woman for President," Clinton said. "Standing here as my mother's daughter's, and my daughter's mother, I'm so happy this day has come."
"Happy for grandmothers and little girls and everyone in between. Happy for boys and men, too, because when any barrier falls in America, for anyone, it clears the way for everyone," she continued. "When there are no ceilings, the sky's the limit."
Clinton was clearly emotional as she walked on stage, and said: "I'm so happy this day has come."
The former secretary of state, introduced by her daughter Chelsea, drew on the historic roots of Philadelphia as a way to reiterate one of her campaign slogans.
"Our Founders embraced the enduring truth that we are stronger together," she said. "America is once again at a moment of reckoning."
Early in her speech, she thanked her formal rival Sen. Bernie Sanders, who urged his supporters to support Clinton despite their differences.
“Bernie, your campaign inspired millions of Americans, particularly the young people who threw their hearts and souls into our primary,” Clinton said.
“And to all of your supporters here and around the country: I want you to know, I've heard you. Your cause is our cause. Our country needs your ideas, energy, and passion,” she said.
Throughout the speech, she took aim at her Republican rival, Donald Trump, casting him as capitalizing on feat to divide the country.
"He's taken the Republican Party a long way, from 'Morning in America' to 'Midnight in America.' He wants us to fear the future and fear each other," she said.
Later she took issue with Trump's comments about the military and his supposed superior knowledge about ISIS.
"A man you can bait with a tweet is not a man you can trust with nuclear weapons," she said.
Throughout her remarks, particularly at the beginning, pockets of protesters jeered and booed at Clinton. Her supporters tried to drown them out with chants of, "Hillary, Hillary."
One of her best-received lines came when she talked about her plans to increase gun control.
"I'm not here to repeal the 2nd Amendment. I'm not here to take away your guns. I just don't want you to be shot by someone who shouldn't have a gun in the first place," she said.
Clinton's speech was the final address of the Democratic National Convention. It was the first time she was formally addressing the convention, though it isn't the first time she's been spotted.
On Tuesday night, hours after she was formally nominated by the roll call and by Bernie Sanders' move for a voice vote, she spoke via video message from New York. And then on Wednesday night, she went on stage to thank President Obama after his speech.
ABC News(NEW YORK) — The Donald Trump campaign said Hillary Clinton's Democratic National Convention speech was "delivered from a fantasy universe," in a scathing rebuke against the newly-minted Democratic presidential nominee.
"Clinton's speech was an insulting collection of clichés and recycled rhetoric," Trump's Senior Policy Advisor, Stephen Miller, said late Thursday night. "She spent the evening talking down to the American people she's looked down on her whole life."
Earlier in the evening, Clinton spoke before thousands at the Wells Fargo Arena in Philadelphia to formally accept her party's nomination.
Shortly after Clinton spoke, Trump fired off a series of Tweets, one of which blasted his election rival for "corruption" and said "devastation" follows her wherever she goes.
No one has worse judgement than Hillary Clinton - corruption and devastation follows her wherever she goes.
ABC News(PHILADELPHIA) -- Two days after the candidacy of Bernie Sanders officially came to an end, supporters of the Vermont senator made their displeasure known on the final night of the Democratic National Convention -- holding up signs saying “liar” and chanting “no more war” during speeches.
Across the Wells Fargo Center, many Sanders' delegates also wore neon yellow, glow-in-the-dark t-shirts with the words, "Enough is Enough" written on them.
However, Sanders delegates received a text message from the Sanders organization asking them to be respectful throughout the evening.
"On Monday when Bernie gave his speech to the Democratic Convention, Secretary Clinton's campaign asked her supporters to be respectful and they were. As a courtesy to Bernie, our campaign would greatly appreciate it if you would extend the same respect during Secretary Clinton's speech," read the text.
Despite the message, the delegation from California unfurled a large banner that said "Wikileaks" -- in reference to the Democratic National Committee email leak scandal -- during a video introduction of Clinton, and many Sanders supporters were spotted in their seats as the rest of the arena rose to greet the candidate as she emerged on stage.
During Clinton's speech, there was sporadic shouting from the crowd that was quickly drowned out by chants of "Hillary."
A few delegates in the California section yelled, "Jill not Hill," in support of Green Party candidate Jill Stein, while others chose to walk out.
"I am no longer a member of the Democratic Party," said Victoria Bard, of Longmont, Colorado (sporting a tie-dye headband and carrying a Jill Stein sign). She, along with half a dozen members of various delegations, walked out Thursday night citing disturbances with Clinton delegates and party staff.
Several Colorado delegates told ABC News prior to the speech that they had no plans to walk out, protest or heckle Clinton during her address Thursday evening. Instead, they wore the t-shirts as a sign of protest against the DNC and solidarity for Sanders.
Cleo Dioletis, 69, told ABC News that the t-shirt wearers were alerted that their credentials would be pulled from the delegation if they showed any "disrespect."
Another Colorado delegate, Tommy Hamrick called the t-shirts a "visual representation" of their support for Sanders, adding it was a message to the press the party is not united.
"It's to give the media a visual of what's in the room," Hamrick said, adding that the shirts are also a "celebration" of "how close [Sanders] got to the nomination."
In the California delegation, several Sanders backers altered signs distributed by convention staff that say "Hillary," changing them to read, "Liar." A number of Californians also held signs directed at Clinton that said "Walk the walk."
Shawn Orgel-Olson, a delegate from Santa Cruz, said that the delegation met Thursday morning and decided their only interruptions Thursday would be "issues focused" and that they would only heckle if a speaker brings up an issue they disagreed with.
ABC News(PHILADELPHIA) — Rep. Joaquin Castro of Texas criticized Sen. Ted Cruz in an interview Thursday, possibly testing a couple of modes of attack that he could use against the polarizing senator in a contest for Cruz's seat in 2018.
“Many Texans have been extremely disappointed in Ted, in his leadership,” Castro told ABC News. “Ted doesn’t work for Texas, he works for Ted.”
Texans haven’t sent a Democrat to the Senate in more than 20 years, but Castro said they “want somebody in there who is not spending every day figuring out where in Iowa they’re going to visit.”
“He is somebody who went to Washington and made it worse,” Castro said of Cruz.
The ambitious San Antonio Democrat, whose future has been an object of speculation among the party faithful gathered in Philadelphia, said he’ll decide in the next couple of months whether to run for the Senate.
The congressman acknowledged that his twin brother, Housing and Urban Development Secretary Julian Castro, was disappointed that he wasn’t selected by Hillary Clinton as her running mate.
“Folks have asked him this week, ‘Hey, were you disappointed that you didn’t become VP?’ How could you not be disappointed that you’re not on a ticket like that?”
“Of course, there is some disappointment, but I think it’s eased when you lost out to somebody who is such a good person and who will help her win in November,” he said of Sen. Tim Kaine of Virginia.
ABC News(PHILADELPHIA) -- Chelsea Clinton, daughter of Democratic Party nominee Hillary Clinton, praised her mother's dedication to public service in her speech introducing the former secretary of state to the DNC, saying that "she never forgets who she's fighting for."
"I'm here as a proud American, a proud Democrat, a proud mother, and a very, very proud daughter," Chelsea Clinton began in her endorsement of her mother.
She described her mother as "wonderful" and "hilarious," and recounted stories about her mother reading "Goodnight Moon" to her. She also described her mother as a devoted grandmother.
Her father, President Bill Clinton, could be seen focusing on the speech intently while she spoke.
She talked about her parents' work on education, and health care.
"Public service is about service," she said about her mother's work as a politician.
She said that her mother would get "straight to work" after hearing about people's problems. She also recounted her mother's losing fight to achieve universal health care in 1994, and how she recovered, getting "right back to work."
Gun violence, criminal justice reform, women's rights, and climate change were issues she said her mother would focus on as president.
"I know with all my heart that my mother will make us proud," she said.
Chelsea Clinton, 36, is remembered as being a shy teenager who grew up in the White House under the glare of the political spotlight. In 2008, she campaigned for her mother in her primary run against then Senator Barack Obama.
The mother of two is married to Marc Mezvinsky, an American former investment banker and co-founder of the hedge fund Eaglevale Partner. Mezvinsky's career as a hedge fund manager came under the microscope at times during Clinton's primary battle with Sen. Bernie Sanders, and was used as ammunition to portray the Clintons as being uncomfortably close to Wall Street, and out of touch with everyday Americans.
Chelsea Clinton's friendship to Ivanka Trump, daughter of Republican nominee Donald Trump, has also been of interest to voters.
The two women haven’t made public appearances together since their parents became political rivals in the upcoming presidential election, but have a friendship through their husbands.
Ivanka Trump recently told People magazine they have remained friends, despite the campaign spotlight.
Adam Schultz for Hillary for America(NEW YORK) -- Outgoing Democratic National Committee Chair Debbie Wasserman Schultz spoke about her resignation during a reception at the party's convention today, saying she “took one for the team” by stepping down from her leadership post.
“This has been a difficult week. There’s no question about it," she said at the reception by the National Jewish Democratic Council. "And I am so proud of my team, some of whom are here, that put [the convention] together, from the convention team, to the national committee staff, to the volunteers, to our donors. Sometimes you just have to take one for the team. And that’s what happened. It's OK."
Video of her remarks was posted on the Jewish Telegraphic Agency's Facebook page.
Wasserman Schultz announced her resignation as chair on Sunday, after WikiLeaks posted nearly 20,000 leaked emails by top Democratic National Committee officials over the course of the primary season.
Several of the emails appear to show Wassserman Schultz growing increasingly frustrated with the Bernie Sanders campaign, with her at one point even referring to his campaign manager, Jeff Weaver, as a "damn liar" and an "a--."
As chair of the party's national committee, Wasserman Schultz was supposed to remain neutral through the primary season, and Sanders and his campaign repeatedly accused her of bias in favor of Hillary Clinton.
Wasserman Schultz was supposed to both open and close the convention. But since announcing that she would step down, she has maintained a very low profile at the event. She has not come onstage, and aside from occasional sightings of her relayed by Twitter users, she has remained out of the public eye. When the Clinton campaign was asked at a briefing today if Wasserman Schultz would be in the arena tonight, campaign staffers said they didn’t know.
The outgoing chair offered effusive praise of Clinton today, telling those at the reception how she supported Clinton even before the candidate announced her run in 2008. Wasserman Schultz said she propelled herself through “the five stages of grief” before supporting Barack Obama that year.
The rest of her remarks that were videotaped were largely spent attacking Donald Trump and emphasizing that the Jewish community needs to rally behind the Democratic Party and Clinton.
She also discussed her next steps. She said she is going home to the Florida congressional district she represents, “winning my primary” -- in which she is in a tight race with Tim Canova, a progressive candidate backed by Bernie Sanders -- to continue her role as a Florida congresswoman and that she will keep fighting for the Democratic Party agenda.
“I am going to be right back out there. I am taking off one hat but putting on another,” she said.
ABC News(PHILADELPHIA) -- In an interview with ABC News on day four of the Democratic National Convention, Joel Benenson, a chief strategist and pollster with Hillary Clinton's campaign, addressed the growing public scrutiny over the Democratic presidential nominee's lack of press conferences.
"We'll have a press conference when we want to have a press conference," said Benenson.
While Clinton has appeared in one-on-one interviews and made various television appearances throughout the campaign, she hasn't fielded open questions at a news conference since Dec. 4, 2015, when she answered seven questions from gathered journalists.
The former secretary of state's lack of appearances in front of the press has been noticed by Republican nominee Donald Trump, particularly as he makes himself available in the same setting every few weeks.
Trump himself has gone so far as to mock Clinton's reluctance to hold a press conference on Twitter, saying in a post on May 31: "I am getting great credit for my press conference. Crooked Hillary should be admonished for not having a press conference in 179 days."
I am getting great credit for my press conference today. Crooked Hillary should be admonished for not having a press conference in 179 days.
"She has answered hundreds, if not thousands, of questions from reporters in one-on-one interviews," said Benenson. "She's doing them every week."
Referring to Trump's comments on the issue, Benenson said, "You're setting up a standard that Donald Trump sets up, of, 'She hasn't had a press conference.'"
In early June, ABC News' Liz Kreutz noted that Clinton "has held just nine press avails with her traveling press corps since January, all of which have lasted 10 minutes or less." Those encounters were informal with small groups of reporters.
"The American people hear from her directly every day. They get to ask her questions every day," said Benenson.
ABC News(NEW YORK) -- Republican presidential nominee Donald Trump said Thursday afternoon he wanted to "hit" some of the Democratic National Convention speakers "so hard" while watching them last night, including a "little guy...so hard his head would spin."
"You know what I wanted to. I wanted to hit a couple of those speakers so hard," Trump said. "I would have hit them. No, no. I was going to hit them, I was all set and then I got a call from a highly respected governor."
Trump didn't immediately clarify what he meant, but he said he was made particularly upset by an unspecified person he called a "little guy."
"I was gonna hit one guy in particular, a very little guy," he said. "I was gonna hit this guy so hard his head would spin and he wouldn't know what the hell happened."
Trump has been campaigning vigorously during the week of the DNC, and has been trying to grab media attention in the process. Yesterday, he held events in Florida, Pennsylvania, Ohio, and hosted a short Ask Me Anything (AMA) session on Reddit in which he spoke to his most ardent supporters.
At the Florida event, he appeared to invite Russia to intervene in U.S. elections by asking the country to retrieve thousands of Hillary Clinton's deleted emails.
"By the way, if they hacked, they probably have her 33,000 emails. I hope they do," Trump told reporters Wednesday morning during a press conference at his golf club in Doral, Florida. "They probably have her 33,000 emails that she lost and deleted."
His campaign immediately tried to walk back his remarks.
3/7 To be clear, Mr. Trump did not call on, or invite, Russia or anyone else to hack Hillary Clintons e-mails today.
Thursday, he wrote off what he said as sarcasm on Fox News.
"Of course I was being sarcastic," the Republican presidential nominee said on "Fox & Friends" this morning.
Before he made the comment about his desire to hit the DNC speakers, Trump accused Sen. Bernie Sanders of "selling out to the devil."
"I was going to say it before. What Bernie should have done instead of selling out to the devil which is what he did, Bernie should have quietly let everything happen, have his protest. He’ll lose, have his protest, go home. He would have gone home a hero," Trump said. "Really, now he's on the other side of the equation except for one thing, trade. He's the only one that gets it."
Trump repeated the sentiment at a rally hosted in Cedar Rapids several hours later, and expressed his desire to "hit this [little] guy so bad."
He said that he was urged to think of his fight against "Crooked Hillary" instead, and that he was advised "don't punch down."
The trip to Iowa was his first return to the state since losing it during the Iowa caucus which took place in February.
ABC News(PHILADELPHIA) -- In an interview with ABC News' David Muir, U.S. secretary of Housing and Urban Development Julian Castro said Hillary Clinton just needs to "be herself" when she takes to the stage this evening to address the Democratic National Convention in Philadelphia and formally accept the party's nomination for president.
"She's been in the public eye now for almost 25 years," said Castro, "and so part of the challenge is, that people are not suddenly going to think of you in a totally different way...I think if folks listen to her, that they will see, as [former] President Clinton said yesterday, who the real person is and instead of the caricature that's been created by the Republicans."
Castro, who spoke with Muir alongside his twin brother, Democratic Rep. Joaquin Castro, at the convention Wednesday, was vetted early in July by the campaign for the vice presidential spot. Sources said that he and Massachusetts Sen. Elizabeth Warren had met with Clinton at her Washington home. Castro would have been the first Hispanic candidate on a presidential ticket.
On July 22, Virginia Sen. Tim Kaine was announced as Clinton's vice president pick. Julian Castro told Muir that not being selected had been a bit of a letdown.
"I'd be lying to you if I said there wasn't a little bit of a disappointment," he said, "but I also know that I'm 41 years old and that God willing, I'm going to have a lot of years left and I know that I got into public service because I felt very blessed with opportunity...Whether I'm in the public sector or the private sector, I'm going to find ways to create more opportunities."
Julian Castro said further that Clinton had made an "excellent choice" with Kaine.
"He is well-prepared. He has been a governor, a senator. He understands the world," Castro said. "He's a great choice for VP."
Rep. Castro, who represents San Antonio in Congress and was scheduled to speak today at the convention, shared with Muir some of what he planned to say.
"I'm going to talk about the reason that people come to this country and that is opportunity and that Hillary Clinton will help create that opportunity and I think Donald Trump will tear it down," he said.
Joaquin Castro said he would not be shying away from using the Republican presidential candidate's name in his speech.
"I'm going to call him out, yeah, directly," he said. "There is a lot of frustration and anxiety in the country but as an elected official and as a politician, you can direct that energy in different ways and he's directed it in a very divisive and negative way and really played on people's fears and resentments."
"This election truly is about a choice we're making between a candidate in Hillary Clinton that has a broad inclusive view of America and in Donald trump someone that has a darker sort of exclusive view of America," Julian Castro said.
