The headline is misquoting him, the full quote is:
“Well, because we all agree that it’s a tragedy having the school hit, and we all agree now for an investigation,” Fetterman said. “What I don’t agree with the rest of my colleagues in the House is that it’s a war of choice, or it’s dumb, or all the things my colleagues have described, you know, this operation. I think it’s a good thing, and I support that.”
Still glaringly stupid, but the headline makes it seem like he’s in denial it happened. He didn’t say the words “leftist” or “craze”


New Republic is definitely left leaning but they are typically factual (citation). This is not their typical fare.
