Two members of an African robotics team who were reported missing from an international robotics competition in Washington, D.C. were spotted crossing into Canada on Thursday morning, authorities said. The D.C. Police Department told Fox News that Don Ingabira, 16, and Audrey Mwamikazi, 17, were seen crossing the northern U.S. border into Canada. Authorities don’t suspect any foul play in the disappearance. WLJA reported the other four teens were reportedly found with family members living in the United States.

President Trump recently intervened to allow 6 Afghan girls into the U.S. to compete in the robotics competition. The Afghan girls were initially denied entry which sparked an outrage. The girls did have a chaperone, so who was assigned to watch over the Burundi team?

After Afghanistan’s all-girls robotics team was denied entry to the United States twice in two months, President Donald Trump has reportedly intervened in the case so the six girls and their chaperon can enter the U.S. to attend a competition next week.
