“First: in the first paragraph of his letter to the president, Holder describes Fast and Furious as a program that was intended “to stem the illegal flow of firearms from the United States to drug cartels in Mexico.” This rank dishonesty suggests that Holder’s letter has primarily a political intent. In fact, the purpose of the Fast and Furious program was to facilitate and even finance the flow of weapons to the Mexican cartels. Why the administration wanted to do this remains a mystery; a mystery that might be cleared up if the subpoenaed documents are produced.”
