Parts of the Texas Capitol were evacuated on Tuesday evening following reports of an active shooter threat. The Texas Department of Public Safety (DPS) said the evacuation, which happened at around 6:30 p.m., was prompted by a threat posted online.

More Texas House Democrats spent the night at the state Capitol in Austin in support of Rep. Nicole Collier, who wasn’t allowed to leave the building after she refused to consent to a police escort. Texas House Republican leaders would only allow Democratic lawmakers to return to their homes if they signed waivers allowing law enforcement to shadow them until a vote on redistricting Wednesday.
