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.

The Texas House gaveled in at noon with Democratic members present, marking an official end to the quorum break.

The first domino in a growing national redistricting battle is likely to fall Wednesday as the Republican-controlled Texas legislature is expected to pass a new congressional map creating five new winnable seats for the GOP.
