The Pennsylvania Working Families Party announced it will be launching a campaign to primary Sen. John Fetterman (D-PA) in 2028, though they have not selected a candidate to run against him yet.

Though the WFP initially supported Fetterman in his 2022 Senate race against Mehmet Oz, the party called him a “Trump-enabling corporate Democrat” in their Tuesday announcement. The decision to primary Fetterman comes in the wake of his support for the GOP-led funding bill to end the government shutdown.
