To talk about this is something Joe Biden can overcome, but Im not going to go so far as to say, I think Joe Biden must drop out. He is too old to be president," Lovett said on the podcast. "A, because I didnt know exactly what was going on behind the scenes, but B, if Joe Biden is the candidate, I want him to f------ win."JON STEWART, 'POD SAVE AMERICA' QUESTION BIDEN'S HEALTH IN WAKE OF 'ORIGINAL SIN' BOOKLovett said he was worried that expressing his concerns would be weaponized against Biden by political opponents.He claimed he kept his concerns to himself to avoid "having the words were saying taken out of context and all of a sudden be part of the case against Joe Biden from the right that would use any person criticizing Joe Biden from the left as a weapon against him.""So it was about being honest about Joe Bidens age as a liability while knowing that if he is the nominee, I want to be clear that I thought it was important to make sure we did everything we could to reelect him," Lovett claimed.CLICK HERE FOR MORE COVERAGE OF MEDIA AND CULTURECNNs Jake Tapper and Axioss Alex Thompson have recently drawn attention to Bidens health while promoting their new book, "Original Sin," which covered the former president's decline and the alleged cover-up by his administration to keep it under wraps.Lovett is featured in "Original Sin" in an anecdote where he and his "Pod Save America" co-hosts Jon Favreau and Dan Pfeiffer met with Biden at the White House on April 26, 2024.
