Biden Says Sickness Will Limit Appearances for His Upcoming Memoir

Former President Joe Biden says his sickness will limit the number of appearances he can make to discuss his upcoming presidential memoir, "Promise Me, America."

In a statement posted Sunday, Biden said the book will be released November 17 and will cover his years in the White House, the challenges he faced and the reasons behind his decisions.

"Some days are better than others. It hasn't stopped me. But sometimes it slows me down," Biden wrote. "What that means is, unfortunately, I won't be able to do as many conversations about my book as I'd hoped."

Biden said his doctors remain encouraged by his response to treatment. He thanked supporters for their prayers and kind words and said he hoped the words in the book would speak for themselves.

The statement does not name appearances that have been canceled or provide a new schedule for the book's promotion.
