Wisconsin is joining a multi-state lawsuit against the Trump administration over an executive order affecting voting.
The order would create voter eligibility lists and restrict mail-in ballots for people not included.
The White House says the move is meant to prevent non-citizens from voting.
Attorney General Josh Kaul says such cases are rare and current systems ensure election integrity.
Kaul joined 22 other attorneys general and a governor in asking a court to block the policy, arguing that election authority belongs to the states.
