Americans returning from trips overseas are often greeted by border officers with a "welcome home." But Abdirahman Aden Kariye, a Muslim American imam living in Bloomington, Minnesota, says there have been no such greetings for him. Kariye, a son of refugees who came to the U.S. from Somalia, told ABC News that his airport experiences are defined by a deep sense of anxiety. He claims he is often "singled out" and taken into private rooms for hours-long interrogations by U.S. border officers.
