The Washington Post reports an executive order signed by Donald Trump "suspends admission of all refugees for 120 days and bars for 90 days the entry of any citizens from seven predominantly Muslim countries, including Iraq, even if they have valid visas." Watch the video below from The Washington Post for a summary of the executive order. Inside Higher Ed has a piece about the executive order. An article in Vox mentions that permanent residents (green-card holders) are being allowed, in some cases, to enter the United States even if they’ve come from one of those seven countries. Apparently, it's on a case by case basis. An article in The Atlantic further explains who is and is not affected by the executive order. I've also included a video clip of Rudy Giuliani talking about how the executive order came together (at approximately the 3:00 minute mark). News keeps coming--the latest development is from White House chief of staff Reince Priebus, "saying that people from the affected countries who hold green cards will not be prevented from returning to the United States."
