Pennsylvania senator who has clashed with party over Israel support says he will reject ‘the extremes and socialism’.

Pennsylvania Senator John Fetterman, a Democrat who has distanced himself from his party, has appeared in a video recording on the first day of the Republican Party’s two-day midterm convention in the United States.

The video on Wednesday was a surprise for those who attended the conservative gathering in Dallas, Texas, where President Donald Trump is seeking to galvanise support ahead of the November elections.

“Yes, I’m Senator John Fetterman, Pennsylvania. Yes, I’m a Democrat. Why am I here talking to you today? Because, well, I’m a common-sense Democrat,” Fetterman said as he introduced his Republican colleague, Senator Dave McCormick of Pennsylvania.

Fetterman, a 57-year-old first-term senator, has cast himself as an outsider within the Democratic Party.

He has offered outspoken support for Israel and the war on Iran, even as voters and progressive voices in his party criticise those elements of US foreign policy.

“I’m always going to stand with America. I’m always going to reject the extremes and socialism and that anti-American way of life,” Fetterman said in the video clip.

But his appearance at the Republican Party’s first-ever midterm convention is likely to exacerbate criticism from his Democratic colleagues.

US Representative Brendan Boyle, another Pennsylvania Democrat, has repeatedly questioned Fetterman’s party allegiance, as well as his commitment to public service. He renewed that sentiment after Wednesday’s video aired.

“A year ago I labeled John Fetterman ‘Trump’s favorite Democrat.’ Tonight, he yet again proves why,” Boyle wrote on social media.

Fetterman has also faced questions about his fitness for office following a series of reports that detail his apparent lack of enthusiasm for his Senate responsibilities.

A recent Wall Street Journal article found that the senator had cancelled meetings with constituents.

In one case, The Wall Street Journal said he skipped a June meeting with injured military veterans, citing illness, only to show up later for a Fox News interview about Israel and its joint war with the US on Iran.

His approval rating is now higher among Republicans in Pennsylvania than among members of his own party.

Last month, a poll from The New York Times, Siena College and The Philadelphia Inquirer suggested that 73 percent of Pennsylvania Republicans approved of Fetterman’s performance, up from 25 percent in 2024.

Meanwhile, Democratic support in the state had slid dramatically over the last two years, slipping from 74 percent to 22 percent. Some 63 percent of Democratic respondents held an unfavourable view of him.

While Fetterman has depicted himself as a maverick within the Democratic Party, he has denied that he would switch parties to become a Republican.

“I’m not going to be a Republican, but I’m going to be a Democrat that’s going to have a conversation with whoever is playing it straight,” he said in a recent interview with Fox News.

Still, speculation about Fetterman’s party credentials has continued as the midterms near.

The election on November 3 will decide which party controls Congress for the final two years of Trump’s term.

Republicans currently hold a small majority in the House of Representatives and Senate, but they could face a setback at the polls as voters express frustration over cost of living issues and Trump’s deepening unpopularity.

Still, reclaiming the Senate especially could be an uphill climb for Democrats. Only a third of Senate seats are up for re-election this year, compared with all 435 House seats.

Fetterman is not up for re-election until 2028.
