A lawsuit filed Friday in downstate Adams County seeks an order recognizing civil arrest warrants issued by the Texas House of Representatives for Democrats who fled to Illinois to thwart a redistricting vote.

In what at least one legal expert called longshot litigation, Texas Republican Attorney General Ken Paxton and Illinois state Sen. Jil Tracy said Friday they asked a court in downstate Quincy to compel Illinois law enforcement to enforce civil warrants issued by the speaker of the Texas House against Democrats who fled their state.

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.
