Fetterman Chief of Staff Cabelle St. John Resigns in 2025

Pennsylvania Senator John Fetterman’s chief of staff has resigned, marking the latest departure in a period of significant staff turnover for the Democratic lawmaker. Cabelle St. John, who has been part of Fetterman’s team since he entered the Senate in January 2023 and became chief of staff in June 2025, will leave the office in the coming weeks.

The resignation follows a pattern of exits that sources familiar with the office link to internal friction over the senator’s political evolution. Former aides have reportedly expressed frustration with Fetterman’s staunch support for Israel following the October 2023 Hamas attacks and his willingness to cooperate with former President Donald Trump on certain issues. These positions are seen as a shift from the progressive profile that initially defined his political career.

One former staff member, who departed in a wave of resignations in 2025, publicly labeled the senator a useful idiot for Republicans. The internal tensions have been mirrored by Fetterman’s own public commentary. During a recent podcast appearance, he criticized his Democratic colleagues, stating the party was becoming more increasingly anti-American for him.
