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.

President Trump criticized Biden's former medical team, suggesting they withheld critical health information from the public.

Former President Biden's diagnosis has divided medical experts over the likely progression of his prostate cancer and resurfaced questions in Washington over his decision last year to run for reelection.
