Texas Republicans are moving closer to approving new congressional maps amid a Democratic show of protest over the GOP House speaker’s order that members who fled the state weeks earlier be placed under law enforcement watch.

A handful of Texas House Democrats were locked in the state Capitol overnight as a protest against a House rule that required members who fled the state earlier this month to be followed by a police chaperone.

A Fort Worth lawmaker’s sit-in on the Texas House floor picked up steam late Tuesday as fellow Democrats flocked to her side for the second night of her round-the-clock vigil after she refused to allow a state trooper to shadow her until the chamber could vote on a new congressional map.
