The Koch-funded Freedom Partners Action Fund has spent more than $6 million on attack ads smearing former Nevada Attorney General Catherine Cortez Masto and lying about her record. Using unlimited corporate and anonymous funding, Freedom Partners dumps millions of dollars on ads to help get people like Congressman Heck elected — because they know he’ll support their extreme agenda in Washington.

“Less known is Freedom Partners Action Fund, a super PAC that shares its name with the Kochs’ secret bank (which has helped fund their efforts). With at least $6 million in donations this cycle from Charles Koch and his trust — and millions more from both Koch brothers in previous years — FPAF has already mounted a multi-million dollar ad campaign attacking Cortez Masto.”
