Texas Attorney General Ken Paxton is asking a California court to recognize civil warrants issued in Texas calling for the arrest and return of House Democrats that left the state to break quorum and prevent a vote on redrawn congressional maps.

The lawsuit from Paxton is one of several ways Texas officials have pressured Democrats to return to the state for a vote on a congressional redistricting expected to add five Republican seats in the U.

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.
