Democrat John Fetterman appeared in a video at the GOP convention ahead of the midterms, with former Republican lawmaker Marjorie Taylor Greene slamming him.

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.
