Democratic Sen. John Fetterman praised his Republican colleague from his home state, Sen. Dave McCormick, in a surprise video appearance at the GOP midterm convention, and condemned the rise of far-left voices in his own party.

The Pennsylvania Democrat has already had a strained relationship with many inside his party. In the video, he spoke about working with Trump but did not outright praise him.

“I’m always going to reject the extremes and socialism and that anti-American way of life,” Fetterman claimed in a brief video message.
