The state of Hawaii is suing President Donald Trump over his executive order temporarily banning immigration from seven majority-Muslim countries and suspending the admission of all refugees to the United States, Hawaii Attorney General Doug Chin announced today during a news conference.

“We did so for one simple reason: everyone in the United States, including the president, must follow the law and follow the Constitution,” said Chin. “The executive order that President Trump issued last Friday keeps Hawaii families apart, it blocks Hawaii residents from traveling, it harms Hawaii’s tourism industry, it establishes a religion in Hawaii in violation of the Constitution, it blocks Hawaii businesses and universities from hiring as they see fit. Most importantly, it degrades the values that Hawaii has worked so hard to protect.”

The lawsuit was filed this morning in Hawaii federal court.

Trump’s order banned immigration for 90 days from seven majority-Muslim countries: Iraq, Iran, Libya, Somalia, Sudan, Syria and Yemen. The admission of Syrian refugees was indefinitely suspended, while the admission of all other refugees was suspended for 120 days.

Washington and Minnesota have also filed lawsuits over the executive order, while a number of other states have joined in a lawsuit filed by the American Civil Liberties Union.
