Former US President Joe Biden’s aides have responded to accusations in the upcoming book “Original Sin” that they concealed his physical decline during the 2024 campaign, including discussions about using a wheelchair. The book claims Biden’s condition was so severe that aides altered his daily routines for safety, while a spokesperson emphasized that signs of aging do not equate to mental incapacity. Additionally, the book notes incidents of Biden forgetting names and recognizing public figures, which contributed to calls for him to withdraw from the race.
