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.

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.

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.
