Texas Governor Greg Abbott threatened on Monday to arrest Democratic lawmakers who are using their collective absence from the state capital to prevent the legislature from adopting a Republican-backed plan for redrawing Texas congressional districts.

Texas Gov. Greg Abbott ordered the arrest Monday of House Democrats after they fled the state to prevent a quorum and a vote on proposed redistricting maps.

Redistricting typically occurs once per decade in each state following the census. But Texas Republicans broke that tradition last week by proposing a new map mid-decade after Trump pushed them to redraw the state’s congressional districts so that the GOP would be more likely to win more seats in the midterm elections next year.
