President Donald Trump strongly suggested that Joe Biden hid his prostate cancer diagnosis from the American people when opining on the news, adding that the alleged omission is worthy of investigation. “It’s a very, very sad situation. I feel very badly about it. And I think people should try and find out what happened,” Trump said Monday.

The president's son suggested there was a cover-up after former president Joe Biden announced his prostate cancer diagnosis.

In 2022, on the 60th anniversary of President John F. Kennedy's Moonshot speech, then-President Joe Biden -- who has had basal cell carcinoma and whose son Beau died in 2015 from a recurrence of brain cancer -- reignited the Cancer Moonshot initiative.

In a copy of “Original Sin” obtained by ABC News, journalists Jake Tapper and Alex Thompson allege Joe Biden hid info about his son Beau's cancer diagnosis.

The Trump administration's cuts to medical research grants have disrupted awards once backed by former President Joe Biden's "Cancer Moonshot" initiative​.

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.

Joe Biden's announcement that he has been diagnosed with prostate cancer has revived questions about what health issues the former US president was dealing with while he was in the White House. In a statement on Sunday, Biden's office said the 82 year old had received the diagnosis on Friday after seeing a doctor for urinary symptoms.
