A federal appeals court on the West Coast said Thursday that it expects to file an order on the case of Donald Trump’s immigration order by end of business day.

Trump’s order restricted travel for people from seven majority-Muslim nations. The Justice Department has defended the order, saying it was a “lawful exercise” of presidential authority.

Last week, a federal judge in Washington state approved a nationwide temporary restraining order against the executive action Friday, saying that the restrictions were unconstitutional. That ruling halted enforcement of the president’s order.

The Justice Department said Monday the ruling in Washington state was “vastly overbroad, extending far beyond the State’s legal claims to encompass numerous applications of the Order that the State does not even attempt to argue are unlawful.”

During his remarks at a law enforcement conference, Trump said the courts blocking his divisive immigration order “seem to be so political.”

Trump’s Jan. 27 order sparked nationwide protests as travelers were detained amid initial confusion about interpretation of the executive order. A number of lawsuits were filed following the chaos, including one submitted by the American Civil Liberties Union and other advocacy groups on behalf of those affected by the restrictions.
