Former Obama speechwriter: Biden's become a liability for Harris

Former Obama speechwriter Jon Favreau said the best thing President Joe Biden can do for the Harris campaign is focus on his final months in office. 

“I would look at the numbers, I would look at the race and say, I’m going to focus on being president over the next couple of days and that’s probably the best thing he can do not just for the Harris campaign, but himself and his legacy too,” Favreau said on CNN's "The Lead with Jake Tapper."
