A new book about former President Joe Biden reports that his mental and physical decline extended beyond forgetting the names of long-time acquaintances and aides.

“Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again,” written by CNN’s Jake Tapper and Axios’ Alex Thompson, hits bookstores May 20.

Among its revelations is that the former president’s physical decline was so severe that aides discussed having him use a wheelchair had he won re-election.

The New York Times is reporting that, according to the book, Biden confused Alabama with Texas during a meeting about abortion rights.

Biden made a statement last year after the Alabama Supreme Court determined frozen embryos are “children,” saying the decision was “made possible” by Donald Trump paving the way to end Roe v. Wade.

“No Democrats in the White House or leaders on Capitol Hill raised any doubts, either privately with the president or publicly, about Biden’s second run,” the book reports.

According to the Times, the book makes extensive use of anonymous sources, which makes it difficult to confirm the accuracy of many of the claims.

Chris Meagher, a spokesman for the former president, said he won’t respond to every story in the book.

“We continue to await anything that shows where Joe Biden had to make a presidential decision or where national security was threatened or where he was unable to do his job,” Meagher said. “In fact, the evidence points to the opposite — he was a very effective president.”
