MADISON, Wis. (AP) — Wisconsin Attorney General Josh Kaul is condemning President Donald Trump’s emergency declaration to pay for a U.S.-Mexico border wall but isn’t saying whether he’ll join a multistate lawsuit challenging it.

California and 15 other states are parties to a federal lawsuit filed Monday alleging the declaration is unconstitutional.

Kaul, a Democrat, issued a three-sentence statement Tuesday calling the declaration a blatant attempt to circumvent constitutional checks and balances. He says he fully expects the courts will block it.

He said that if federal funds meant for Wisconsin are diverted as a result of the declaration the state Department of Justice would take the “appropriate action.” He didn’t say what that might entail. His spokeswoman, Gillian Drummond, didn’t immediately respond to an email.
