Just theorizing here but maybe word is out in Liberia etc that if you have Ebola you can get free and excellent treatment in the US//// To get past screeners w thermometers in Liberia you just take acetaminophen.
So you get here and Ron Klain will whisk you away far from prying eyes and embarrassing publicity to a top flight med center
I am sure that the word is out in Liberia, and with lots of Liberians already living here, we will keep getting them no doubt.
However, some may believe the racist claims, and decide to go to some other country.
