During a four-hour visit, Trump met with local officials and toured the border between the United States and Mexico.

Seconds after Sanders took the stage for a rally in Seattle, a dozen protesters from the city's Black Lives Matter chapter jumped barricades and grabbed the microphone on August 8, 2015. Holding a banner that said "Smash Racism," two of the protesters -- Marissa Johnson, left, and Mara Jacqueline Willaford -- addressed the crowd. Sanders stood just feet away off stage, chatting with his wife and the three aides that came to Seattle with him. His aides said the senator had no plans of leaving during the protests, but once Johnson did not appear willing to give up the mic after a moment of silence, organizers effectively shut down the event. Sanders never addressed the crowd, but he did make his way through it to shake hands and take pictures. Elaine Thompson/AP

He was the one person that really -- and there were a couple of others -- but Ted Cruz was out there and he backed me very strongly." Pete Marovich/Bloomberg via Getty Images

Donna Brazile, acting chairwoman of the Democratic National Committee, talks with Reince Priebus, chairman of the Republican National Committee, before the vice presidential debate. Brazile later resigned from her role as a CNN contributor amid fresh revelations that she sent questions to Clinton's campaign in advance of a CNN debate and a CNN-TV One town hall. In a statement, CNN said it was "completely uncomfortable with what we have learned about her interactions with the Clinton campaign while she was a CNN contributor." CNN said it "never gave Brazile access to any questions, prep material, attendee list, background information or meetings in advance of a town hall or debate." RICK WILKING/REUTERS/Newscom

Among those attending the second debate were, from left, Kathleen Willey, Juanita Broaddrick and Kathy Shelton. Less than two hours before the debate, those three -- along with Paula Jones -- appeared in a Trump news conference to speak out against the Clintons. Willey, Broaddrick and Jones have previously accused Bill Clinton of inappropriate sexual behavior. Shelton's rapist was defended by Hillary Clinton as a young lawyer. That man was convicted of a lesser charge and served 10 months in jail. Scott Olson/Getty Images

Attorney Gloria Allred, left, holds a news conference with Summer Zervos, a former contestant on "The Apprentice" who has accused Donald Trump of grabbing her breast and kissing her aggressively in 2007. The presidential candidate disputed Zervos' allegations in a statement on October 14, 2016. "When Gloria Allred is given the same weighting on national television as the president of the United States, and unfounded accusations are treated as fact, with reporters throwing due diligence and fact-finding to the side in a rush to file their stories first, it's evident that we truly are living in a broken system," Trump said. At a rally that day in Charlotte, North Carolina, Trump called himself a "victim" as more women continued to come forward accusing him of sexual assault and harassment. "I am a victim of one of the great political smear campaigns in the history of our country," he said. Frederick M. Brown/Getty Images

Clinton listens to Trump speak at the Al Smith charity dinner in New York on October 20, 2016. The annual event benefits Catholic charities and is often one of the final opportunities for presidential candidates to share a stage before the election. Historically, it has been a good-natured roast -- but CNN's Stephen Collinson said Clinton and Trump struggled to disguise the anger, bitterness and sheer open dislike that has pulsed through the race.

Clinton and aide Huma Abedin stand aboard Clinton's campaign plane as they head to Cedar Rapids, Iowa, for a campaign rally on October 28, 2016. News broke on the flight that the FBI was reviewing new emails related to Clinton's personal server, bringing an issue they had assumed was behind them back into the campaign. The emails being examined were part of an investigation into former U.S. Rep. Anthony Weiner, Abedin's estranged husband, who is accused of sexting with a girl who was purportedly underage. On November 6, 2016, FBI Director James Comey told lawmakers that after reviewing the new emails, the agency stood by its opinion that Clinton should not face criminal charges.
