A Texas Democrat has stayed overnight at the state Capitol to protest how the Texas House’s top Republican had dozens of her colleagues shadowed.

After weeks spent out-of-state in an effort to deny Texas Republicans a quorum for an extreme redistricting plan—designed at Donald Trump’s behest to give the GOP a five-seat advantage in the House of Representatives—the state’s Democrats are still refusing to back down.

Democratic Texas state Rep. Nicole Collier spent the night on the Texas House floor in protest after refusing a Republican demand to be placed under the watch of the state Department of Public Safety.

Democratic state Representative Nicole Collier spent the night in the Texas Capitol building rather than agree to a police monitor amid a contentious partisan struggle over redistricting that is part of President Donald Trump's campaign to keep the national House of Representatives in Republican hands.

An elections expert said on Sunday that the Texas Republican Party made a "critical" admission about their redistricting efforts, which could cause their efforts to backfire. For the last month, the Texas GOP has tried to pass a new election map that would eliminate five Democrat-controlled seats.

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.
