Pennsylvania Sen. John Fetterman was taken to the hospital Wednesday after a U.S. Senate event.
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.
