Questions are mounting about Pennsylvania Democratic Senator John Fetterman’s ability to continue serving, after recent reports that former and current staffers are increasingly concerned about his erratic behavior. Fetterman, who had a stroke in 2022, had run as a progressive but has sharply shifted to the right. In May 2024, his former chief of staff wrote a 1,600-word email to the medical director of the traumatic brain injury and neuropsychiatry unit at Walter Reed expressing concern over Fetterman’s mental health, including his “conspiratorial thinking; megalomania … and rambling.”

New York magazine reveals that in a private meeting in February, Fetterman spoke against Israel’s then-ceasefire, saying, “Let’s get back to killing.” During a discussion on Gaza and the Palestinians, he reportedly said, “Kill them all.” In February, The Intercept reported there had been an exodus from Fetterman’s staff in part due to his shift on Israel and his willingness to work with President Trump. Many of Fetterman’s small donors have also asked for him to return their campaign donations to him.
