WASHINGTON (AP) — U.S. Sen. John Fetterman has been hospitalized after feeling lightheaded while attending a Senate Democratic retreat. Fetterman suffered a stroke last year while campaigning. In a statement Wednesday night, the office of the Pennsylvania Democrat says initial tests do not show evidence of a new stroke. The senator’s communications director, Joe Calvello, says in the statement that doctors are running more tests and that the senator remains at George Washington University Hospital for observation. Fetterman’s defeat of celebrity heart surgeon Mehmet Oz was critical to Democrats maintaining their Senate majority.
