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.

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 the announcement that Biden has an aggressive form of prostate cancer, Trump Jr. initially reposted a message on X (formerly Twitter) wishing Biden a “speedy recovery” and writing, “Agree 100%.” But he quickly pivoted to attack mode, taking aim at former first lady Jill Biden, who holds a doctorate in education and is not a medical doctor.

President Donald Trump on Monday questioned the timeline of former President Joe Biden's recent cancer diagnosis, saying it was "dangerous" for the United States that the public was not informed sooner.

President Donald Trump trusts White House doctors despite Biden's prostate cancer diagnosis. White House press secretary Karoline Leavitt assured reporters that Trump's health is excellent.

Ezekiel Emanuel, a prominent Democratic figure, told “Morning Joe” the former president "did not develop [prostate cancer] in the last 100 to 200 days."

Biden led the Obama administration’s Cancer Moonshot initiative, which he also reinstated in 2022 after he was elected president. Its mission was to slash the cancer death rate by at least 50 percent over the next 25 years, preventing 4 million deaths and improving the lives of patients and their families.
