From the what-separation-of-powers department:
The Department of Homeland Security has an update on the entry ban:
The Department of Homeland Security will continue to enforce all of President Trump's Executive Orders in a manner that ensures the safety and security of the American people. President Trump's Executive Orders remain in place—prohibited travel will remain prohibited, and the U.S. government retains its right to revoke visas at any time if required for national security or public safety. President Trump's Executive Order affects a minor portion of international travelers, and is a first step towards reestablishing control over America's borders and national security.
The NY Post adds:
The ACLU is getting "multiple reports" that federal customs agents are siding with President Trump — and willfully ignoring a Brooklyn federal judge's demand that travelers from seven Muslim countries not be deported from the nation's airports.

And banning valid visas and green cards is much broader than banning applications for entry. You can't insult your way out of a logical argument the way Trump does. He actually doesn't get out of them either, he just ignores people and keeps doing what he wants. You may see that as some sort of "strong man gets it done" attitude, which if you care to be honest with yourself is just your desire for a dictator to come in and force all the dirty liberal "progressives" to go along with conservative xenophobia. As someone else mentioned, it seems more likely this is a calculated move to appease the Trump supporters and polarize the country even further.
