Clout learns there’s been some serious turnover in Sen. John Fetterman’s office. In the last month, all three of Fetterman’s top communications staffers have left Capitol Hill.

Nick Gavio, who was deputy communications director, will leave the office at the end of March to take a new role with the Working Families Party. Fetterman’s former communications director, Joe Calvello, left earlier this month to work for Chicago Mayor Brandon Johnson.

And Emma Mustion, a press and digital aide also left Fetterman’s office to work on the reelection of Sen. Bob Casey.
