Several Texas state House Democrats ripped up the written agreements that allowed them to leave the chamber with a police escort and returned to the House floor Tuesday night, the caucus announced.

Democratic state Representative Nicole Collier spent the night in the Texas Capitol building rather than agree to a police monitor that is part of a contentious partisan struggle over redrawing voting districts to keep the national House of Representatives in Republican hands.

Republicans in the Texas House forced returning Democrats to around-the-clock surveillance by state Department of Public Safety officers to leave the floor.
