Retired U.S. diplomats on Monday accused the Customs and Border Patrol of a "deeply troubling pattern" of discrimination and harassment against Black, Hispanic and other minority members re-entering their own country. The American Academy of Diplomacy, which groups former U.S. officials in international affairs, urged Secretary of State Mike Pompeo in a letter to order a review of incidents, "ensure equal treatment" of minority U.S. diplomats and make clear their mistreatment is "unacceptable."
