(WHTM) – Pennsylvania U.S. Senator John Fetterman says if the United States House of Representatives can reach a deal to avoid a government shutdown, he’ll ditch his signature hoodie and shorts for a suit.

Fetterman’s statement comes after the Senate adjusted its formal dress code, drawing ire from many Republicans, and as lawmakers debate how to avoid a government shutdown with less than two weeks until the deadline.

“If those jagoffs in the House stop trying to shut our government down, and fully support Ukraine, then I will save democracy by wearing a suit on the Senate floor next week,” said the first term Senator.

Fetterman had been avoiding wearing a suit and tie on the floor by voting from the Senate doorway.

The changes prompted outrage from some of the chamber’s more formal members, eroding a bit of the good will that first-term Fetterman had earned earlier this year when he checked himself into the hospital for clinical depression. He won bipartisan praise for being honest about his diagnosis, which came in the wake of a stroke he suffered on the campaign trail last year. When he returned from treatment, he started donning the more casual clothes, which he says make him more comfortable.

Kansas Sen. Roger Marshall, a Republican, said it’s a “sad day in the Senate” and that the people who Fetterman and Schumer represent should be embarrassed.

“I represent the people of Kansas, and much like when I get dressed up to go to a wedding, it’s to honor the bride and groom, you go to a funeral you get dressed up to honor the family of the deceased,” Marshall said. Senators should have a certain level of decorum, he added.

Republican Sen. Susan Collins of Maine agreed, arguing that the relaxed rules debase the institution of the Senate. “I plan to wear a bikini tomorrow to the Senate floor,” Collins joked.

Asked about the criticism, Fetterman feigned mock outrage.

“They’re freaking out, I don’t understand it,” he said of his critics. “Like, aren’t there more important things we should be working on right now instead of, you know, that I might be dressing like a slob?”

For Fetterman, his signature hoodies and gym shorts were a sign of his recovery. Before he checked himself into the hospital, his staff had asked him to always wear suits, which he famously hates. But after a check with the Senate parliamentarian upon his return in April, it became clear that he could continue wearing the casual clothes that were often his uniform back at home in Pennsylvania, as long as he didn’t walk on to the Senate floor. He still wears suits to committee meetings when they are required.

In recent weeks, the Pennsylvania senator has become more comfortable joking around in the hallways and answering reporters’ questions. His words are still halting sometimes due to his stroke and an auditory processing disorder that makes it harder to speak fluidly and process spoken conversation. He uses iPads and iPhones in conversations that transcribe spoken words in real time.

“I think we should all want to be more comfortable,” Fetterman told a group of reporters on Monday. “And now we have that option, and if people prefer to wear a suit, then that’s great.”
