Cnn Talk With Max Foster

It's official: Joe Biden wants to get back into the White House, this time in the top job. He's formally announced his candidacy for U.S. President, with a dramatic campaign video and a message aimed directly at Donald Trump. Biden joins a crowded field of Democrats, becoming the 20th person vying for the party's nomination.

Max Foster anchors a conversation with Greg Swenson of Republicans Abroad, Journalist and Author Rachel Shabi, and LBC's Iain Dale. via Knit
