Karl Rove formed several entities under 501 C 4, 5, & 6. They are all bound by the same laws that tax expempt organizations are. They ca take contributions for political campaigns. But they can not take over 50% of monies received.
501 C 4,5& 6 are supposed to be social welfare non profit organizations to help the community such as food banks. Unfortunately Mr. Rove did not follow those guidelines, because thousands of people from groups all over the country began to ask the U.S. government to audit Mr. Rove's group, which was funding huge dollar amount campaign attack ads for much more than the required 50%.
In short they are finding that the 501 C 4, 5, & 6 are frauds. Below are the government documents. If this is the original email, I will also attach the government documents.
This was researched by Sharon, founder of Save The Sacred Sites Alliance (not to be confused with the fake Save Sacred Sites which liked our name and decided to steal it.)
