Is this yet another sign of constitutional decadence, or is it a step into modernity for the fusty, antiquated chamber? Either way, it's the best news ever for Sen. John Fetterman (D-Pa.), who would prefer to do business while looking like he's on a Saturday-morning jog.

Not everyone is happy.

"The Senate chamber isn't your home, a gym, or an outdoor park," wrote former congressman Justin Amash (I-Mich.) in a post on X, formerly known as Twitter. "If you can't dress professionally for work on the floor of the Senate of the United States, then do us all a favor and get a different job."

Senate Majority Leader Charles E. Schumer (D-N.Y.) recently directed the chamber's sergeant-at-arms to no longer enforce its unwritten, selectively enforced dress code of business attire, handing senators the power to wear whatever they want on the Senate floor — although it seems like Sen. Kyrsten Sinema (I-Ariz.) has been doing that for quite some time (see: her denim vest, her neon tiger prints, her various wigs, her dilophosaurian sleeves).
