This goes back to the 1990s, when Haley Barbour was running the RNC.

Triad Management Services, a conservative consulting firm, billed itself as a privatized Republican national coalition. The agency had ties to Kansas Republican Senator Sam Brownback, one of the members of the Senate Governmental Affairs Committee. Triad may have acted illegally during the 1996 campaign when it acted as an intermediary during the 1996 election campaign. It coordinated political activity by tax-exempt groups and by laundering money from wealthy donors through PACs to GOP congressional candidates. Triad founder Carolyn Malenick admitted that GOP candidates occasionally funneled their donors to Triad which in turn advised the donors to contribute to PACs that were likely to support the candidate. Triad also coordinated attack ads run by tax-exempt groups against Democratic candidates. . . .
Ben Ginsberg, a former general counsel of the RNC, represented secret trusts that also contributed to Triad groups. The Koch family, which owned the Kansas-based Koch Industries, gave heavily to tax-exempt groups linked to Triad, using one of the trusts represented by Ginsberg. Senate investigators sent Charles Koch a letter in October 1997, asking to speak with him about their inquiry, but he has failed to respond. According to FEC records Koch brothers and Koch PAC contributed directly to more than a dozen of the candidates supported by three tax-exempt groups they had funded.
Koch Industries was investigated by a congressional committee for allegedly stealing oil from Osage native American reservations and federal property by intentionally taking more oil than it paid for. In a report that led to a grand jury probe, the committee concluded that Koch Oil, the largest purchaser of Indian oil in the country, illegally and deliberately stole the native Americans oil. No one was indicted, and Nickles nominated Koch to a federal judgeship.
