Demonstrators hold placards during a protest outside of John F. Kennedy International Airport against U.S. President Donald Trump’s executive order blocking visitors from seven predominantly Muslim nations in New York on Saturday, Jan. 28. A U.S judge temporarily blocked the Trump administration from enforcing an executive order that would have led to the deportation of refugees and visa-holders from seven mostly Muslim countries. The ruling by U.S. District Ann Donnelly in Brooklyn came at an emergency hearing Saturday night, hours after the American Civil Liberties Union and other groups sued to halt the Jan. 27 order.
