Scoop: Fetterman's chief of staff resigns

Sen. John Fetterman's chief of staff resigned Wednesday, a source familiar with the move told Axios.

Why it matters: The Pennsylvania Democrat has had a serious staff retention problem as he's faced scrutiny over his health struggles and changing political brand.

Driving the news: Cabelle St. John has served on Fetterman's team since he first came to Washington about three-and-a-half years ago. She became his chief of staff in 2025.

• Her official last day will be in the coming weeks.
• Fetterman, who was once a darling of the progressive movement, has seen major turnover as ex-aides have grown frustrated with his steadfast support for Israel and warmer approach toward President Trump.
• Former staff have also complained about working with him on an interpersonal level.

The other side: Fetterman initially did not respond to a request for comment.

• After the story published, he downplayed this staff turnover in a text to Axios.
• "So much for the turnover issue. Clicks!" he wrote, posting an image that showed other offices with purportedly higher turnover.
