North Carolina junior Senator Thom Tillis is among those questioning President Donald Trump’s executive order on immigration, after two Iraqis, who had visas and had helped US forces in the War on Terror, were detained at New York’s JFK airport. Tillis signed onto a letter with Democratic Senators Claire McCaskill and Jeanne Shaheen, to Defense Secretary James Mattis asking that he "encourage the President to immediately ensure that properly vetted Iraqis who supported the U.S. mission in their country can continue to enter the U.S.” Tillis has said the executive order need "refining."
