Sen. John Fetterman, D-Pa., unloaded on his own party on Sunday evening, blasting a series of victories for progressives he called “anti-America.”

“Big night for the dirtbag left,” Fetterman said, referring to New York’s recent primaries, where two members of the Democratic Socialists of America (DSA) won primaries.

“I’ve said the party is becoming an orgy of socialism. Clearly anti-America, anti-Western Civilization,” Fetterman said.

Fetterman’s striking calls give a rare look at how some moderates may view the developments on their far-left flank that have dominated the party’s momentum in recent months, sparking concern that their high visibility is dragging the party further and further left.

His comments come on the heels of a handful of key progressive victories.

In Maine, Graham Platner, a controversial Democratic candidate for U.S. Senate, has attracted controversy for denying knowledge of the meaning behind a Nazi-linked tattoo, for off-color comments about race and calling himself a “communist” in a deleted Reddit post.

In New York, one DSA member, Claire Valdez, won a primary on a platform of abolishing ICE and a Green New Deal-style approach to climate change. Similarly, Darializa Avila-Chevalier, another DSA candidate, beat out incumbent Rep. Adriano Espillat, D-N.Y., a high-ranking Democrat and the chair of the Congressional Hispanic Caucus.

Both Chevalier and Valdez had the backing of New York Mayor Zohran Mamdani, himself a socialist.

The wins have captured national attention and drawn criticisms from Republicans who have pointed to their success as emblematic of the direction of the Democratic Party.

Fetterman, who has not shied away from confrontations, has been one of the few Democrats to express alarm about the kind of candidates carrying the party’s banner.

“I mean, you look at some of the things that people have said. Abolish prison, abolish the border, abolish ICE, I mean these crazy people — I have colleagues in my caucus that refuse to even call this out,” Fetterman said.

“Between P-hustle in Maine and some of the other winners in New York, they should form their own party and run on all the things that they’ve had to delete on social media,” Fetterman said, referring to Platner.

“That’s where our party has moved,” he added.
