Sen. John Fetterman has checked himself into a hospital to receive treatment for clinical depression, his office said Thursday.

“Last night, Senator John Fetterman checked himself into Walter Reed National Military Medical Center to receive treatment for clinical depression,” a statement from the Pennsylvania Democrat’s office said. “While John has experienced depression off and on throughout his life, it only became severe in recent weeks.”

According to the statement, Fetterman was evaluated by a Congress physician on Monday, who recommended in-patient care at Walter Reed Medical Center.

“John agreed, and he is receiving treatment on a voluntary basis,” his office said. “After examining John, the doctors at Walter Reed told us that John is getting the care he needs, and will soon be back to himself.”

Gisele Barreto Fetterman, Fetterman’s wife, tweeted out the statement, adding, “After what hes been through in the past year, theres probably no one who wanted to talk about his own health less than John. Im so proud of him for asking for help and getting the care he needs.”
