@MTAGKnudsen joins lawsuit on behalf of Montana, Brnovich wrote on Twitter Tuesday morning, adding that a preliminary injunction had been filed. Montana Attorney General Austin Knudsen has also joined the Arizona lawsuit, and both states have filed a motion for a preliminary injunction to block the policy from going into effect as the case is heard. A DHS spokesperson could not immediately be reached for comment. Montana Attorney General Austin Knudsen joined the updated lawsuit after Arizona Attorney General Mark Brnovich reframed it around interim guidance issued by Immigration and Customs Enforcement last month. "If asked about the poorest policy choice Ive ever seen in government, this would be a strong contender," Brnovich said in a statement.
