The officials say Trump’s executive order targeting refugees and nationals from seven predominantly Muslim countries hurts their states’ economies. They say it also disrupts education and medical services and violates First Amendment-protected religious liberties.

Trump has argued the U.S. must protect its borders from would-be foreign terrorists.

Government lawyers are expected to file court papers later Monday.
