Watch a former chairman of the Congressional Black Caucus and House Africa Subcommittee, the late Democratic California congressman Mervyn Dymally (1926 – 2012), deny that slavery still exists in Mauritania. Dymally was a paid “legislative advocate” (lobbyist) for the Mauritanian government, bought with a yearly $120,000 salary. His testimony sought to refute that of Cotton and the American Anti-Slavery Group at the same March 13, 1996, House hearing.
