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.
