Biden's health, both physical and mental, was discussed at length during the 2024 presidential election cycle, more recently after excerpts from a new book by CNN 's Jake Tapper and Axios' Alex Thompson, Original Sin: President Biden's Decline, Its Cover-Up, and His Disastrous Choice to Run Again, were published by multiple media outlets.

Biden, even after he has exited political life and as he faces a serious cancer diagnosis, remains a factor in the conversation about his party's political future.

After a stretch of limited public appearances since leaving office, former President Joe Biden’s cancer diagnosis arrived amid heightened scrutiny of his cognitive health.

President Donald Trump said Monday he was “surprised” the public didn’t know about former President Joe Biden’s cancer diagnosis sooner—a comment that came after other Republicans, including Vice President JD Vance, appeared to insinuate Biden may have hidden his cancer diagnosis from the American public while he was in office.

“Last week, President Joe Biden was seen for a new finding of a prostate nodule after experiencing increasing urinary symptoms. On Friday, he was diagnosed with prostate cancer, characterized by a Gleason score of 9 (Grade Group 5) with metastasis to the bone,” the statement from Biden’s office said.
