Dept. of Justice Cites 'National Security' in Calling for Trump Immigration Order Reinstatement

The Ninth Circuit motions panel has not made a decision.

"The State argues...that the injunction does not impose any irreparable harm. But the injunction reinstates procedures that the President determined should be temporarily suspended in the interest of national security," the reply brief to the 9th Circuit Court of Appeals, filed Monday evening, says.

"The potential national-security risks and harms resulting from the compelled application of procedures that the President has determined must be reexamined, for the purpose of ensuring an adequate measure of protection for the Nation, cannot be undone. Nor can the effect on our constitutional separation of powers."

Today, the appeals court scheduled oral arguments in the case for 3 p.m. PT on Feb. 7.

Early Sunday morning, the 9th Circuit rejected the DOJ's request for an emergency stay on the restraining order.

“The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned!” Trump tweeted on Saturday.

Trump has also tweeted that if something happens while his executive order is blocked, to blame the judge in the case.
