WASHINGTON (AP) — No shorts on the Senate floor. The Senate voted Wednesday evening to reverse an informal guidance issued by Senate Majority Leader Chuck Schumer last week that senators could wear what they want when voting or speaking in the chamber. The resolution, passed by voice vote with no objections, requires that ”business attire be worn on the floor of the Senate, which for men shall include a coat, tie, and slacks or other long pants.” It did not specify what women should wear.
