Rep. Sheila Jackson Lee, a Texas Democrat, was arrested Thursday as she engaged in a voting protest in Washington, D.C.

The congresswoman and others were standing in front of an entryway to the Senate Hart Building before officers with the Capitol Police instructed the group that it was their “third and final warning” to disperse from the area, according to video footage posted by Jackson Lee’s office. Soon after the declaration, law enforcement cuffed Jackson Lee and other demonstrators with zip ties and led them into a police van.
