Fetterman's chief of staff leaves amid string of departures

Pennsylvania Sen. John Fetterman’s chief of staff is leaving her post, two people familiar with the matter confirmed to POLITICO on Tuesday. The move is yet another key departure for a congressional office that’s been marked by turnover amid mounting questions about the Democrat's health and shifting political persona.

Axios first reported Krysta Sinclair Juris’ plans to part ways with Fetterman’s office.

POLITICO has learned Cabelle St. John, who previously served as Fetterman’s deputy chief of staff, senior adviser and scheduling director, is taking over as his new top aide.

“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 said 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.”

In the last year and a half, the senator’s former chief of staff, Adam Jentleson, top communications aides and legislative director all left his team. Two more aides departed Fetterman’s office in the last couple months.

In a Monday debate in Boston with Sen. Dave McCormick (R-Pa.), Fetterman said that reporting about his missing votes and committee hearings is a “weird smear.” Previously, he criticized a New York magazine article about former and current aides who expressed concerns about his health “a one-source hit piece.”

“I’m here. I’m doing that job,” he said in the debate that aired on Fox Nation. “For me, if I miss some of those quotes — I mean some of those votes — I’ve made 90 percent of them and, and we all know those votes that I’ve missed were on Monday; those are travel days, and I have three young kids, and I — those are throwaway procedural votes. … That’s a choice that I made, and if you want to attack me for that, go ahead.”

In addition to concerns over his health, some ex-staffers have been frustrated with Fetterman's hardline support of Israel and recent meeting with President Donald Trump.
