Reply to "Just call me Nemo":  Trump did NOT select the countries named in his ban on travel.  Those countries were selected by the Department of Homeland Security during the previous administration.  ---------- From the Department of Homeland Security website, article title:  "DHS Announces Further Travel Restrictions for the Visa Waiver Program" (February 18, 2016) ----- quotes: "the Secretary of Homeland Security has determined that Libya, Somalia, and Yemen be included as countries of concern....The three additional countries designated today join Iran, Iraq, Sudan and Syria as countries subject to restrictions ....The addition of these three countries is indicative of the Department’s continued focus on the threat of foreign fighters."
