The Hill reports that Senator John Fetterman (D-Pa.) has checked himself into Walter Reed National Military Medical Center to receive treatment for clinical depression, according to a statement from his chief of staff. Fetterman's depression became severe in recent weeks, but he has had experience with it off and on throughout his life. The senator agreed to the inpatient care on a voluntary basis after being evaluated by the Attending Physician of the United States Congress. Doctors have stated that he is receiving the care he needs and will soon be back to himself. This situation follows Fetterman's hospitalization just over a week ago due to feeling lightheaded during the Senate Democratic retreat, though he was released the following day with no evidence of a seizure or stroke.
