Senator John Fetterman, D-Pa., has stated he will remain a Democrat, despite making a surprise video appearance at the Republican National Committee's midterm convention to introduce colleague Sen. Dave McCormick, R-Pa. Republicans have previously welcomed the idea of Fetterman potentially switching parties.

In a statement, Fetterman described his remarks as introducing McCormick as "a great American and friend." He added, "We are in different parties, but we are both Team PA." Fetterman highlighted their joint efforts to secure funding for Pennsylvania, improve transportation and housing, and support the "Steel Way of Life."

"I’m a lifelong Democrat who votes overwhelmingly with my party — and should the Senate flip in November, I will still be the 51st vote that I ran on," Fetterman said, asserting his continued commitment to the Democratic Party. He began his Senate career after a narrow victory over Dr. Mehmet Oz in 2022, campaigning on a progressive platform that contributed to a slim Democratic majority.

However, Fetterman has also positioned himself as a "commonsense Democrat" who rejects socialism and has on occasion challenged the party's direction. He previously warned he would consider leaving the Democratic Party if it adopted more anti-Israel policy positions. He has also criticized the rise of progressive voices within the party.

Fetterman has reportedly diverged from Senate leadership, including Minority Leader Chuck Schumer, D-N.Y., on several issues, such as former President Donald Trump's actions in Iran and voting with Republicans on a government shutdown measure. Senate Majority Leader John Thune, R-S.D., has indicated that Senate Republicans have had discussions with Fetterman about his challenges within his caucus and would welcome him to the Republican conference.
