The point of Carson’s trip, which starts Dec. 27, appears to be to bolster his foreign policy knowledge, which he has admitted is a weak spot. Carson says he wants to learn about Boko Haram from Nigerians directly.

Another important goal may be to streamline his personal narrative. Carson, once a popular black American icon who grew up in inner city Detroit and became one of the country’s leading neurosurgeons, may be thinking of the president he routinely criticizes. Obama’s Kenyan roots, at first ammunition for his detractors, eventually became a credit to his worldliness and ability to relate to immigrants, as well as to African Americans.

Carson first claimed his East African ancestry—specifically his roots in Turkana, a semi-nomadic pastoralist community—after critics accused him of not understanding slavery when he called the president’s healthcare law, the Affordable Health Care Act, “the worst thing since slavery.” Defending his comment, Carson said in July that his family had experienced slavery. Two of his ancestors, a brother and a sister, had been sold to different slave owners. “The pain and the heartache associated with that era… There is nothing that compares to it,” he said at the time.
