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 federal judge temporarily blocked the Trump administration from enforcing an executive order that would have led to the removal from U.S. airports of refugees, visa holders and legal U.S. residents from seven mostly Muslim countries. U.S. District Judge Ann Donnelly in Brooklyn issued the ruling following an emergency hearing Saturday night, hours after the American Civil Liberties Union and other groups sued to halt President Donald Trump’s Jan. 27 order.
