President Trump lashed out at the appeals court judges who are presiding over the lawsuit challenging his executive order banning people from seven majority-Muslim nations from entering the United States.

President Donald Trump: “If you were a good student in high school or a bad student in high school, you can understand this. And it’s really incredible to me that we have a court case that’s going on so long. And it couldn’t have been written any more precisely. It’s not like, 'Oh, gee, we wish it were written better.' It was written beautifully.”

That’s President Trump, speaking in Washington, D.C., Wednesday to a conference of law enforcement officials. During his comments, he also called the deliberations “disgraceful.” Trump’s attack comes after he went on a Twitter rant over the weekend against federal Judge James Robart, calling him a “so-called judge” after Robart issued a nationwide injunction halting Trump’s Muslim ban.
