Joe Biden’s White House doctor’s uncooperativeness in a House probe looking into the former president’s fitness to serve has led the Republican congressman overseeing the investigation to allege a “coverup” of Biden’s “cognitive decline.”

Biden’s former White House physician is refusing answer questions as part of the House Republican investigation into Biden’s health in office.

Republican members of the House Oversight and Government Reform Committee balk at the refusal. Democrats say Congress should focus on the health of the people.
