A high-ranking member of Mexico's Sinaloa drug cartel operative in US custody alleges that Operation Fast and Furious was part of an agreement to finance and arm the Sinaloa cartel in exchange for information used to take down rival cartels, according to court documents. The statement was made by Jesus Vicente Zambada-Niebla, the Sinaloa cartel’s “logistics coordinator” in charge of arranging massive drug shipments from Latin America to the United States.
