CNN host Jake Tapper and Axios reporter Alex Thompson are releasing a book on former President Joe Biden‘s mental decline during his time in office.

Tapper notoriously defended Biden’s mental acuity dating back to 2020. Throughout his term, Biden stumbled on his words, which was often chalked up to his former stutter. Biden eventually dropped out of the 2024 race and endorsed his running mate, former Vice President Kamala Harris.
