An active shooter threat at the State Capitol Tuesday pushed a protest in solidarity with Rep. Nicole Collier out along the street.

Rep. Nicole Collier is one of dozens of Democrats who fled Texas earlier this month to block a vote on a Trump-backed redistricting plan.

Texas Republicans assigned law enforcement to escort specific Democrats to and from the statehouse after dozens left to block a vote on redistricting.

The grounds were cleared after 7 p.m. as a demonstration was about to begin but lawmakers and staff members were allowed to remain inside the Capitol.

Protesters were evacuated from the Texas Capitol grounds Tuesday evening after the Texas Department of Public Safety (DPS) said someone posted on social media calling on others to go to the building and "take action by shooting and killing those who will not allow lawmakers to leave.

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.

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 in a statement.

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

The Minnesota group statutorily charged to assess the status of security at the state Capitol complex will meet this midweek for the first time since the lawmaker shootings in June.
