Many lawmakers frequently wear jeans or casual shoes to the House floor, particularly during the first vote series of the week that are usually close to dinnertime.

“Members should wear appropriate attire during all sittings of the House, however brief their appearances on the floor may be. You know who you are,” Boehner said to laughter.

Boehner also reminded lawmakers not to take pictures while they are on the House floor. Photography is prohibited in both the House and Senate chambers.

“Members should refrain from engaging in still photography or audio or audio recording in the chamber. Taking photographs detracts from the proceedings and presents security and privacy challenges for the House,” Boehner said.
