Has the Obama administration quietly adopted features of Trump's Muslim Visa Ban?

In the last week, we learn this: that former editor-in-chief of Al-Quds Al-Arabi, `Abdul-Bari `Atwan (one of the most widely read Arab columnist) has been denied visa to visit the US.  That was less surprising than the decision delivered to Druze warlord, Walid Jumblat (a known tool of US foreign policy who switched sides after 2005 and went from being a tool of the Syrian-Iranian axis to being a tool of the Saudi-US axis) that his visa application has been denied.
