Trump pulls U.S. out of U.N. Compact on Migration

Citing American Sovereignty, Ambassador Nikki Haley, U.S. Permanent Representative to the United Nations said,

"No country has done more than the United States, and our generosity will continue. But our decisions on immigration policies must always be made by Americans and Americans alone. We will decide how best to control our borders and who will be allowed to enter our country. The global approach in the New York Declaration is simply not compatible with U.S. sovereignty."
