The standoff began on Monday, when Democratic members returned to the Capitol after being out of the state for more than two weeks due to a controversial redistricting map. Rep. Collier refused to agree to leave the chamber under the surveillance of the Department of Public Safety.

This is just my way of resisting,” said Texas state Rep. Nicole Collier after Republicans ordered Democrats to be monitored by police if they left the statehouse again.

After Democrats returned to the Texas statehouse, Republican leadership assigned law enforcement officers to monitor them to prevent further delays to their plan to redraw congressional voting districts to favor Republicans ahead of the election.

Texas Rep. Nicole Collier agreed to return to the state after fleeing to delay a vote on GOP gerrymandering, but declined to sign anything—and so, Republicans locked her in the Capitol.

Texas Republicans mandated that Democratic lawmakers not be allowed to leave the state house without a permission slip and a police escort.
