The book takes aim at the final days of Joe Biden as president and is titled “Original Sin: President Biden’s Delcine, Its Cover-up, and His Disastrous Choice to Run Again.” Among the topics discussed was the accusation in the book that Biden’s aides thought he might eventually need a wheelchair to get around.

Jake Tapper and Alex Thompson’s new book is an investigative account of loyalists and family members who shielded the diminished president from full public view.
