Rep. Nicole Collier, the Democratic state lawmaker who spent Monday night inside the Texas Capitol, is asking a court to let her exit the building, alleging she’s facing “illegal restraint by the government” after she was told she needs a police escort to leave.

The Fort Worth lawmaker and dozens of other Democrats left Texas earlier this month to delay a vote on a GOP-led plan to redraw the state’s congressional map.

The Democrats returned to Texas in recent days and they were given state police escorts to ensure they will show up when the state House convenes Wednesday, but Collier refused to sign a “permission slip” to be under escort by the Texas Department of Public Safety. Collier says she slept on the House floor overnight.
