Sen. John Fetterman, D-Pa., one night after attending the State of the Union address with other members of Congress, stayed in the hospital last night.
Joe Calvello, Fetterman's communications director, stated in a statement to journalists that Fetterman started to feel unwell while he was attending a Senate Democratic retreat.
That necessitated the use of a pacemaker and a defibrillator, and Fetterman stated that he had previously been diagnosed with atrial fibrillation, a heart rhythm disorder that can interfere with blood flow.
According to Calvello, "initial tests did not show evidence of a new stroke." However, the senator's doctors wanted to conduct additional tests and keep him in their care for the night.
Days after attending the Democratic National Committee's winter meeting in Philadelphia with other Democrats, Fetterman received news of his most recent hospitalization.
