By Democratic Sen. John Fetterman of Pennsylvania will cross more than the political aisle Wednesday night when he appears by video at the Republican Party’s midterm convention in Dallas to praise President Donald Trump and Republican Sen. Dave McCormick’s work on behalf of the American steel industry.
Fetterman is expected to introduce McCormick during the unusual appearance, which the Republican senator helped arrange after cultivating a close relationship with his Democratic counterpart, Axios reported. Fetterman reportedly will not announce that he is leaving the Democratic Party, but he plans to criticize the socialism increasingly associated with its left wing.
Democratic Senator John Fetterman’s remarks at the GOP midterm convention…

The video marks another striking break between Fetterman and a party that once regarded him as a rising progressive star. It will air less than eight weeks before the Nov. 3 midterm elections at an event Republicans have billed as a two-night “Trump-a-Palooza,” an extraordinary attempt to recreate presidential-year enthusiasm with Trump serving as the featured speaker both evenings.
The appearance also carries significance in Pennsylvania, where Fetterman and McCormick have developed one of the Senate’s most unconventional political partnerships. The two men formed a joint fundraising committee, Common Ground PA, in July, allowing them to raise money together despite belonging to opposing parties. Fetterman said in August that he would “absolutely” refuse to campaign against McCormick, whom he called his friend.
Their cooperation has included support for the revised agreement allowing Japan’s Nippon Steel to acquire U.S. Steel. The transaction, completed in June 2025, included approximately $14 billion in promised investments and a federal “golden share” giving the U.S. government veto power over major corporate decisions. Trump approved the arrangement after former President Joe Biden blocked an earlier version of the deal on national-security grounds. McCormick played a prominent role in advancing the agreement, which retained U.S. Steel’s Pittsburgh headquarters and required American leadership at the company. The Associated Press reported that the protections included an American CEO, a majority-American board and federal approval over certain corporate actions.
Fetterman’s convention appearance is nevertheless likely to deepen suspicions among Democrats that his estrangement from the party has moved beyond occasional bipartisanship. He has repeatedly praised Trump on issues including steel, Iran and Israel while criticizing Democrats for moving left on border security and foreign policy.
Israel has produced the clearest divide. Fetterman remained one of Israel’s most outspoken Democratic supporters as much of his party turned against its military campaign in Gaza. In April, he opposed two Senate resolutions supported by most Democrats that would have blocked certain weapons sales to Israel. He also backed Trump’s approach during the conflict with Iran and opposed Democratic-led efforts to restrict the president’s war powers.
Fetterman said in July that he would leave the Democratic Party if it became “the anti-Israel party.” He otherwise insisted, “I’m never changing my party,” except for “that one condition.”
His domestic-policy defections have also accumulated. Fetterman voted to advance Markwayne Mullin’s nomination as secretary of homeland security, angering Democratic colleagues, while a recent Wall Street Journal investigation alleged that he had shown limited interest in routine Senate responsibilities as he focused on Israel and appearances in conservative media. Fetterman disputed that account.
The hostility is no longer confined to private Democratic conversations. Rep. Brendan Boyle, D-Pa., responded publicly to the convention news, writing on Twitter: “John Fetterman is a disgrace.” Other Pennsylvania Democrats have discussed challenging Fetterman in a 2028 primary if he seeks reelection, though the senator has not announced whether he will run.
A recent New York Times/Philadelphia Inquirer/Siena University poll found that Pennsylvania Republicans viewed Fetterman more favorably than they viewed McCormick. That reversal illustrates Fetterman’s increasingly unusual political position: a Democratic senator facing mounting opposition from his own party while becoming more popular among voters across the aisle.
The appearance recalls Democratic Sen. Zell Miller’s speech at the 2004 Republican National Convention, when the Georgia Democrat endorsed President George W. Bush and condemned his own party’s approach to national security. Fetterman is not expected to go that far Wednesday night, but appearing at a Republican convention to praise Trump while denouncing socialism will ensure that questions about his political future are not going away.
