Right-wing author and conspiracy theorist Jerome Corsi sued his former associate Roger Stone for defamation on Thursday.

The lawsuit, filed in the U.S. District Court for the District of Columbia by Corsi who is seeking $25 million in damages, alleges Stone lied and threatened Corsi as both men tried to distance themselves from allegations they had prior knowledge of WikiLeaks email dumps that were damaging to Hillary Clinton's 2016 campaign.

The lawsuit compares Stone's behavior to that of a member of the Mafia.
