PA Sen. John Fetterman: Latest Medical Update

WASHINGTON, D.C. — Pennsylvania Sen. John Fetterman remains hospitalized after becoming lightheaded at a Democratic Senate event on Wednesday, but his aides said he did not suffer another stroke. Fetterman had a near-fatal stroke last year while campaigning for the Senate.

Fetterman communications director Joe Calvello said the results of an MRI and other tests eliminated the possibility of a second stroke.

“He is being monitored with an EEG for signs of seizure - so far there are no signs of seizure, but he is still being monitored,” Calvello said in a statement provided to CNN.

Calvello did not indicate when Fetterman might be able to leave George Washington University Hospital.

Shortly before last year's election, which Fetterman won by defeating celebrity doctor Mehmet Oz, Fetterman's doctor released the results of an exam amid concerns that Fetterman's health problems might prevent him from assuming his duties if elected.

Dr. Clifford Chen said that Fetterman was "recovering well from his stroke and his health has continued to improve."

Fetterman's cardiologist said last year that Fetterman suffers from both atrial fibrillation and cardiomyopathy.

Fetterman, 53, is Pennsylvania's former lieutenant governor and the former mayor of Braddock, a municipality near Pittsburgh.
