Sen. John Fetterman is losing another one of his staff members amid growing, reported concerns over his well-being.
The Pennsylvania Democrat’s chief of staff, Krysta Sinclair Juris, will be leaving his office soon and will be replaced by Cabelle St. John, who previously worked as his deputy chief of staff, senior adviser, and scheduling director. Axios was the first to report the news on Tuesday.
“Cabelle St. John has been a trusted advisor since day 1 in the office. I’m lucky to have her taking over as my Chief of Staff and I’m confident she’ll do a great job,” Fetterman told Axios in a statement. “I’m grateful for Krysta’s work. She’s been an invaluable member of the team for over two years and I wish her all the best.”
Over the past year and a half, a pool of Fetterman’s staff, including top communication aides and his legislative director, have left his office with two aides even departing as recently as May.

Fetterman’s former chief of staff Adam Jentleson, whom Juris succeeded, also left his post and notably expressed his concern over the senator’s health in an explosive report for New York Magazine last month, where he argued that Fetterman was “struggling in a way that shouldn’t be hidden from the public.”
The senator subsequently brushed off New York Magazine’s report as a “hit piece,” and told NBC News in a statement: “It’s a one-source story, with a couple of anonymous sources, hit piece from a very left publication. There’s really nothing more to say about that.”
He again scrutinized the growing, reported concerns over his health as a “weird smear” campaign against him during a debate in Boston on Monday.

“For me, it’s very clear. It’s just part of this weird, this weird smear,” the senator said. “I’m here. I’m doing that job. I’m defending all those things, and all of those important votes, I’ve always been there.”
According to tracking by GovTrack.us, Fetterman missed 174 out of 961 roll call votes, or 18.1 percent of votes from February 2023 to May 2025, and more than 21 percent of the votes in the last Congress. The median of votes senators have missed is 2.9 percent.
