Last June, during the first presidential debate of the 2024 U.S. election campaign, Joe Biden stumbled and struggled to find the right words. His performance was described as disastrous and incoherent.

At that point, many Americans had already come to the conclusion that Biden was too old for the job. But for those who hadn't yet, the debate was the moment that fact became impossible to deny.

Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again is a new book that investigates Biden’s cognitive and physical decline in recent years, and the attempt by a small group of loyalists and family members to keep it from public view.

Journalists Jake Tapper and Alex Thompson did over two hundred interviews with lawmakers, White House officials, and campaign insiders for it.

Despite the reporting, Joe Biden continues to reject concerns about his age. His recent diagnosis of an aggressive prostate cancer has brought his health back into the spotlight.

Today on Front Burner, Axios’ National Political Correspondent Alex Thompson on his new book, and the political consequences of Joe Biden’s decline.
