Calling Donald Trump “the most dangerous president in modern history,” Sen. Bernie Sanders endorsed former Vice President Joe Biden for president, less than a week after Sanders ended his own presidential bid. Sanders made a split-screen appearance in a livestream hosted by Biden, telling him “We need you in the White House. And I will do all that I can to make that happen.”

Sanders made clear his message to his supporters: ”I am asking all Americans—I'm asking every Democrat, I'm asking every independent, I'm asking a lot of Republicans—to come together in this campaign to support your candidacy which I endorse.”
