In November Senator Charles Grassley (R-IA) began investigating six evangelistic ministries for the possible illegal use of donations to finance lavish lifestyles. Four of the six have not responded to Grassley's inquiries and now, Senator Max Baucus (D-MT) the Senate Finance committee chair has joined the effort. Baucus and Grassley sent letters to the groups with a March 31 deadline urging them to cooperate. Some of the targeted ministries argue that their financial information is private and of no concern to the Senator. Importantly, Baucus has subpoena power, which may be the only way to get the information. Their letter states; "One of the roles of the Finance Committee . . . [is] the exercise of oversight over . . . the Internal Revenue Service to make sure that its rules and procedures meet the purpose and intent of the revenue code, including those rules applicable to non-profit organizations. In order to do this effectively, the Committee needs to understand clearly and specifically how non-profit organizations are structured and operate."
