WASHINGTON (AP) — Before Pennsylvania Sen. John Fetterman checked himself into a hospital for clinical depression in February, he used to walk the halls of the Senate stone-faced and dressed in formal suits. These days, he’s back to wearing the hoodies and gym shorts he was known for before he became a senator. People close to Fetterman say his more relaxed style is a reflection of the progress he’s made after six weeks of inpatient treatment for clinical depression. He was treated with medication and fitted for hearing aids for hearing loss that had made it harder for him to communicate. His hospitalization came less than a year after he had a stroke during his Senate campaign.
