Up to 40 state Democratic parties could be implicated in an alleged scheme to illegally funnel some $84 million to Hillary Clinton’s 2016 presidential campaign, according to a new report.

A federal lawsuit says the Clinton team and the Democratic National Committee went around campaign finance laws by pouring money into state parties that then sent the funds back to the DNC to help Clinton, the Las Vegas Review-Journal reported.

The Committee to Defend the President, a pro-President Trump PAC, first filed a complaint with the Federal Election Commission in December. But the authorities didn’t take action before a required deadline, the group’s campaign finance attorney, who filed the federal lawsuit, told the Review-Journal.

The FEC complaint alleges “an unprecedented, massive, nationwide multi-million dollar conspiracy” in which Dems and Clinton’s camp were “effectively laundering nearly all contributions” given to the Hillary Victory Fund.

That fund is a so-called joint fundraising committee that allowed Clinton to raise money for her campaign and local state parties simultaneously. Possible due to looser campaign finance rules, this type of fund meant Clinton could raise $350,000 or more from a single rich donor.

Backer said most money raised for state parties by the Hillary Victory Fund were then passed back to the DNC and on to Clinton’s campaign.

“You had individuals giving $300,000,” Backer told the Review-Journal. “They’re not doing it because they care about Nevada’s or Arkansas’ state party. They’re doing it to curry favor with and buy influence with Hillary Clinton.”
