On February 19, the Ninth Circuit refused to stay the order of the U.S. District Court of Washington state, in State of Washington v Donald Trump, 25-807. This is the case in which President Trump’s executive order on citizenship had been enjoined. The three judges who handled the matter in the Ninth Circuit are William Canby, a Carter appointee; Milan D. Smith, a Bush Jr. appointee; and Danielle J. Forrest, a Trump appointee.
The order is very brief, and says that Trump has not shown there is an emergency. Judge Forrest wrote separately to expand on that point.
It is somewhat likely that Trump will now ask the U.S. Supreme Court to issue a stay.
