I just found this on a "THE HILL" article, In early January, the Trump transition team sought clear answers from the State Department to a set of probing questions: 1) “With so much corruption in Africa, how much of our funding is stolen?” 2) “We’ve been fighting al-Shabaab for a decade, why haven’t we won?” 3)   “How does U.S. business compete with other nations in Africa? Are we losing out to the Chinese?” 4) “Why should the U.S. continue the Africa Growth and Opportunity Act (AGOA) which provides massive support to corrupt African regimes?”  These questions have yet to be answered adequately."  It is from an article from 2017 but the answers are probably still much the same.  https://thehill.com/blogs/pundits-blog/foreign-policy/323198-trumps-suspicion-of-foreign-aid-to-africa-is-right-on-the
