Texas Attorney General Ken Paxton has filed suit seeking to force Illinois authorities to assist with returning nearly three dozen Democrats who fled to block a vote on a GOP redistricting plan.

Illinois law enforcement officers should be allowed to arrest Texas House Democrats who have been staying in the Chicago area this week, Attorney General Ken Paxton argued in a lawsuit filed Thursday evening.

The attorney general is calling on the “full faith and credit” clause of the U.S. Constitution, which says states should typically honor each other’s judicial proceedings.
