The Trump administration will be expanding its ban on travel for citizens of certain countries to more than 30, Homeland Security Secretary Kristi Noem said, in the latest restriction to come since a man from Afghanistan was accused of shooting two National Guard members. The expansion would build on a travel ban already announced in June by the Republican administration, which barred travel to the U.S. for citizens from 12 countries and restricted access to the U.S. for people from seven others. In a social media post earlier this week, Noem had suggested more countries would be included.
