Sen. John Fetterman (D-Pa.) said in an interview that aired Sunday that he believed opening up to the public about his mental health struggles earlier this year would negatively impact his career.

In an interview with NBC’s Kristen Welker on “Meet the Press,” Fetterman opened up about his battle with clinical depression earlier this year and urged those facing mental health issues to seek help. He said that for the first couple of weeks while being treated for depression at Walter Reed National Military Medical Center, he felt scared about sharing his experiences publicly.
