Rep. Lauren Boebert, R-Colo., blasted Democratic Senator John Fetterman's "unbecoming" decision to attend a Senate press conference while wearing a hoodie and shorts.

"John Fetterman redefined Casual Friday on a Thursday morning," Boebert wrote on Twitter. "It’s truly unbecoming for someone to show up like that to any job, let alone a job that only 100 people are elected to do."

The Pennsylvania senator attended a Thursday news conference to discuss debt limit negotiations wearing a white hoodie, gray workout shorts, and running shoes, while standing alongside four fellow Democratic Senators who all were dressed in a suit and tie.

"There’s just no excuse for it," the Colorado Republican said in her tweet blasting Fetterman's Senate attire.

Fetterman initially checked himself into the hospital in February, and did not return in-person to the Senate until April.

On his first appearance in the chamber since his weeks-long hospital stay, the Senator was seen wearing a black Carhart hoodie and blue casual shorts.
