Michael Moore mocked President Trump on Saturday for criticizing the judge who ruled against the immigration order.
The documentary filmmaker tweeted, "Thank you, So-Called President Trump! I've been struggling for 2 weeks over what to call you, and your tweet here gave us the answer."
His post was in response to Trump's earlier tweet which read, "The opinion of this so-called judge, which essentially takes law-enforcement away from our country, is ridiculous and will be overturned!"

The target of Trump's disapproval is U.S. District Judge James Robart who issued a temporary stay against the administration's immigration order on Friday.
Lawmakers and others have also criticized the president's comment; Senator Chuck Schumer tweeted, "POTUS's attack on Judge Robart shows a disdain for an [independent] judiciary that doesn't bend to his wishes & lack of respect for the Constitution."
Meanwhile former vice presidential candidate Tim Kaine said on Twitter, "Many judges now restraining President Trump's immigration orders. Mr. President — don't attack judges, fix your bad policy!"
Republicans have been less vocal, but Senate Majority Leader Mitch McConnell said onCNN, "I think it's best not to single out judges for criticism."
