Former President Biden provides update on new book and health

(NBC, KYMA) - Former President Joe Biden posted to X Sunday night, providing an update on his upcoming book and on his health.

In the post, former President Biden stated he would not be able to do many conversations on his memoir, citing his battle with cancer.

The former president writes that he has responded well to treatment, but "some days are better than others...[and] sometimes it slows [him] down."

He continues by saying he's "hopeful the words on the page speak for themselves."

The former president's memoir titled "Promise Me, America" comes out November 17.

Biden was diagnosed with an aggressive form of prostate cancer in 2025, and has been receiving treatment since.
