U.S. Senator John Fetterman remains hospitalized at a medical facility in Pennsylvania after experiencing lightheadedness at a Senate Democratic retreat.

Doctors have ruled out a second stroke for the senator, but are monitoring him for signs of seizure. Tests have been conducted and no new stroke has been identified.

According to a spokesman, Fetterman did not suffer a stroke but is being monitored for “signs of seizure.”

The news comes after Fetterman was first hospitalized on Feb. 9 following feeling lightheaded at the retreat. A statement from Fetterman’s office said he was being hospitalized as a precautionary measure and that he was in good spirits.

The senator has since been receiving care and treatment while in the hospital. The hospitalization was initially expected to last a few days, but it has since been extended as doctors continue to monitor him.

At this time, no further updates have been provided on Fetterman’s condition.
