Mapping all the countries from which President Donald Trump’s executive order would restrict travel to the United States.

A sweeping new travel ban on citizens from a dozen nations was announced by the White House on Wednesday, reviving a defining effort from the first Trump administration to crack down on entries from specific countries.

President Donald Trump has banned citizens of 12 countries from entering the United States and restricted access for those from seven others, citing national security concerns in resurrecting and expanding a hallmark policy of his first term that will mostly affect people from Africa and the Middle East.
