Texas’ Republican attorney general and a GOP Illinois state senator filed a petition in more conservative Adams County rather than where Texas lawmakers are located in suburban Chicago.

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.
