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.

While President Trump’s response was surprisingly muted, Don Jr. and J.D. Vance are already casting blame and floating conspiracy theories.

President Trump said Monday that he was surprised that Joseph R. Biden Jr.’s cancer diagnosis was not made public a “long time ago,” seeming to suggest without evidence that the former president’s cancer was not newly discovered and had been covered up.

Trump Jr. suggests a coverup in the aftermath of Joe Biden's cancer diagnosis. He said Jill Biden, who doesn't have a medical degree, should've known.

A former Fox News contributor turned Trump administration Department of Justice lawyer has suggested Joe Biden’s wife could be criminally charged for “elder abuse.” The former president announced a diagnosis of a particularly “aggressive” prostate cancer on Sunday.

Donald Trump apparently believes Joe Biden has “Stage 9” cancer. There is no such thing as “Stage 9” cancer, but Trump repeated that twice Monday while talking to reporters about the former president’s revelation that he has aggressive prostate cancer that has spread to his bones.

“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.
