Donald Trump and Republican allies are accusing President Joe Biden of concealing his aggressive prostate cancer diagnosis, revealed just this week, and linking it to ongoing concerns about Biden’s cognitive health. Trump expressed surprise the public wasn’t informed sooner and questioned whether the White House had intentionally kept the information hidden. The claims come amid renewed scrutiny following a new book that alleges the administration downplayed signs of Biden’s mental decline. Biden, 82, thanked supporters for their well-wishes as debate around his health intensifies.
