Sen. John Fetterman (D-PA) rejected the notion of any “sinister” plot behind his new joint fundraising venture with Sen. Dave McCormick (R-PA), a rare cross-party ordeal that was met with fresh fury and speculation from Democrats that the centrist could switch parties.

“It’s nothing sinister,” Fetterman told the Washington Examiner in a brief interview Wednesday at the Capitol. “It’s pretty much — people have joint interest in the things that we happen to agree on, if we both represent Pennsylvania.”
