False reports that President Joe Biden had a “medical emeregency” while traveling on Air Force One Friday circulated widely on social media after he arrived home in Delaware after a campaign stop in Wisconsin. The posts provided no evidence that such an event occurred. An Associated Press reporter traveling with Biden on Air Force One said there were no signs of any problems. He departed the plane on his own, saluted and spoke with an officer at the base of the stairs and took a question from a reporter before leaving.
