A new book by journalists Jake Tapper and Alex Thompson is shedding new light on the cognitive decline of former President Joe Biden. The book, "Original Sin," depicts alleged attempts by the president's family and close aides to shield his mental lapses from the public.

I don’t think it was a cover-up," said California Democrat Rep. Ro Khanna, "but I do think that the advisers and people close to Joe Biden owe an explanation."

Jake Tapper admitted the Biden White House lied about the "cheap fakes" claim nearly a year after CNN pushed the talking point to viewers while the president was seeking re-election.

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.

She accused the authors of being “irresponsible self-promoting journalists out to make a quick buck” and called their work “a bunch of unoriginal, uninspired lies.”

The Wall Street Journal called out CNN anchor Jake Tapper for downplaying the paper's report on former President Biden's mental decline in June 2024.

Rep. James Clyburn (D-SC) spoke to CNN's Jake Tapper on "State of the Union" about the Republicans' proposed budget and President Biden's mental acuity during his presidency.
