'The Ship Has Sailed': Boothe on Possible Biden 2020 Run

Biden Didn't Run in 2016 for Fear of Clinton's 'Stop at Nothing' Opposition Research

Former Vice President Joe Biden sat down with Stephen Colbert on "The Late Show" Monday night to discuss his new book and the state of the country one year after President Donald Trump's election victory.

Biden said what's happening in the U.S. right now is a “battle for the soul of this country."

"How many of you are now worried about the stability of the republic? How many are now worried about this new phony nationalism and its ‘us against them’? How many are worried about this populism designed to essentially undermine the essence of the Bill of Rights?" Biden said. "I think people are worried."

Colbert noted that the last time Biden was a guest on the "Late Show" he said Trump should be given an "even shot" at doing the job.

“Have we given him enough of a shot at this point?” Colbert asked.

Biden said that Trump's reaction to the riots in Charlottesville, Virginia, was a turning point.

Trump was criticized by many for not condemning strongly enough violence perpetrated by white supremacists and neo-Nazis.

“Charlottesville, for me, was a moment where I thought silence would be complicity,” he explained.

“The idea that you would see, in America, in a historic city, Nazis carrying flags, spouting the same bile about Jews that was spouted in Germany in the 30s, and then these guys crawling out from under rocks with torches, and to not have an outright flat condemnation of that," Biden said. "I thought the silence was deafening.”

He added that it's not just the president, and he finds Steve Bannon and the alt-right to be "reprehensible."

He said he hopes that the Trump presidency will go down as "the single exception in American history."
