WASHINGTON (AP) — Sen. John Fetterman acknowledges having “dark conversations” about harming himself before he hit “the emergency brake” and sought treatment for depression. In an interview with NBC’s `”Meet the Press,” the Pennsylvania Democrat described his thoughts at that time as, “I can’t be a blueprint for my children. I can’t let them be left alone or not to understand why he would have done that.” So he checked himself into Walter Reed National Military Medical Center last February. Fetterman wondered whether he’d survive politically. He said that “when it got released where I was and where it was going, it was a big story. And so, I had assumed that that would be the end of my career.”
