US President Donald Trump and Joe Biden return to the campaign trail on Wednesday after a chaotic debate that allowed the 77-year-old Democratic candidate to rebuff Republican claims that he doesn't have the stamina for the White House job.

Snap polls on the debate performances of the presidential candidates leaned towards Biden, who withstood a barrage of barbs from the 74-year-old Trump while delivering some of his own.

A CBS sampling of 1,039 likely voters who watched the televised debate held in Cleveland, Ohio, had Biden edging Trump by 48 percent to 41 percent -- a margin similar to that of the national polls heading into the November 3 election.

President Trump refused to condemn white supremacists during the first of three scheduled presidential debates with Joe Biden. When pressed by moderator Chris Wallace of Fox News to disavow far-right extremism, Trump name-checked the Proud Boys and told them to “stand back and stand by,” words widely denounced as a tacit endorsement of the violent, white supremacist organization classified by the Southern Poverty Law Center as a hate group. The Proud Boys almost immediately responded by changing its logo online to include the Trump quote. Christian Picciolini, a former neo-Nazi who now leads the Free Radicals Project, a group focused on helping people disengage from violent extremism, says Trump’s words were a clear encouragement for “continued violence” from far-right groups. We also speak with Temple University professor Marc Lamont Hill, who says Trump’s performance at the debate is a continuation of his white supremacist project. “He wants violence in the streets, he wants chaos at the polls, because he wants Americans to feel a sense of unsafety. It’s its own kind of diplomatic terrorism,” he says.
