Megyn Kelly talks to Jake Tapper, co-author of "Original Sin," to talk about his viral interview with Lara Trump, his reflections on past coverage, and more. Tapper said at the time he "interpreted" Lara Trump's comments as mocking Biden's stutter.

Former President Joe Biden’s physical deterioration was severe enough in the second half of his presidency that his aides privately discussed putting him in a wheelchair for his second term, according to a new book from CNN’s Jake Tapper and Axios’ Alex Thompson.

Jon Stewart began his monologue Monday by showing a montage of CNN anchor Jake Tapper promoting his new book, Original Sin, to his viewers. The book is an apparent bombshell tell-all about Biden’s mental decline in the White House.

According to the book, some top officials were left wondering whether Biden was truly the one making calls, or whether his aides were subtly steering outcomes.

CNN’s Jake Tapper delivered a fierce pushback Friday after Joe Biden's team attempted to downplay newly released audio of the former president appearing to struggle with memory lapses during a special counsel interview.
