Which countries will fall under the noose of Noem's travel ban?

Donald Trump 's Homeland Security Secretary has revealed plans for a 'full travel ban' on countries that are sending 'killers, leeches and entitlement junkies' to the United States after a meeting with the president. Kristi Noem did not specify which countries would be banned but her announcement follows an attack on two National Guard members in Washington DC last week.
