Only a few House members remained in the chamber late Wednesday night, preparing to vote on dozens of bills that would pass by voice vote. After six hours on the floor, Rep. Thomas Massie, R-Ky., stood up and demanded that a quorum is in effect.

It seems like demanding a record of the vote is a small act, but Massie’s defiance against Speaker Paul Ryan, R-Wis., had more profound implications. Massie took a stand against Ryan after House leadership added an amendment to the Farm Bill that suspended Congress’ war powers. Massie’s demand for Congress to reassert its constitutional powers and know what they’re voting on has caused a headache for the House GOP.
