Obama Administration released Bin Laden’s arms dealer on April 4 and sent him to Senegal in West Africa.

From the Department of Defense:

On Aug. 20, 2015, the Periodic Review Board consisting of representatives from the Departments of Defense, Homeland Security, Justice, and State; the Joint Chiefs of Staff, and the Office of the Director of National Intelligence determined continued law of war detention of Umar does not remain necessary to protect against a continuing significant threat to the security of the United States. As a result of that review, which examined a number of factors, including security issues, Umar was recommended for transfer by consensus of the six departments and agencies comprising the Periodic Review Board. The Periodic Review Board process was established by the president’s March 7, 2011 Executive Order 13567.
