The state of Minnesota is suing the Trump administration over the president's executive order that temporarily bans refugees and travelers from seven predominantly Muslim nations from entering the United States.
Minnesota Attorney General Lori Swanson on Wednesday night joined the attorneys general of Washington state, New York, Virginia and Massachusetts in taking legal action against the ban.
"The executive order that imposes blanket entry restrictions to the United States for people from certain countries is unconstitutional," Swanson said in a statement.
"It does not pass constitutional muster, is inconsistent with our history as a nation, and undermines our national security," Swanson wrote. "America can keep its people safe without sacrificing bedrock constitutional principles."
The suit, with Minnesota and Washington as plaintiffs, names as defendants President Donald Trump, Homeland Security Secretary John Kelly, Acting Secretary of State Tom Shannon and the federal government.
Rep. Tony Cornish, R-Vernon Center, said "he's not applauding" Swanson for her decision to sue.
"I'm a supporter of clamping down on immigration, thorough vetting and making our country safe," Cornish said. "I represent outstate, rural Minnesota. The majority of them support Trump and reform of immigration."
In separate but parallel lawsuits, the attorneys general of New York, Virginia and Massachusetts are joining suits filed in their respective federal courts. And at least four U.S. District Court judges have issued rulings to block portions of the executive order.
