The Capitol grounds were closed as protesters gathered in support of Rep. Nicole Collier, who is staying on the House floor in protest.

The Texas State Capitol was cleared of visitors Tuesday evening and closed to the public after a social media threat, the Texas Department of Public Safety said.

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.

After weeks of delays, Texas Republicans who control the state House are slated to begin the process for their controversial redistricting plan.

Texas Republicans insisted that Democrats have around-the-clock police escorts to ensure they wouldn’t leave again.

Collier is among the Texas House Democrats who broke quorum to block mid-decade congressional redistricting. She and at least 51 other lawmakers left the Capitol to block a map that opponents say would disenfranchise voters and position Republicans to gain five seats in Congress.

Shortly after, a protest formed inside the Capitol with chants in support of Collier, including four women sitting outside the doors of the chamber Monday night surrounded by dozens of Texas DPS officers. An officer told them, "If you do not leave, you're subject to arrest for trespassing," and then they were handcuffed and taken into custody.
