Conservative provocateur James O’Keefe is facing a $1 million federal lawsuit over his group’s undercover video sting against Democratic organizations and activists in the weeks before last year’s presidential election.

O’Keefe and his organization posted some of the videos online last October, purporting to show efforts by Democrats to provoke violence at Donald Trump’s campaign rallies and events.

The recordings led two Democratic operatives, Robert Creamer and Scott Foval, to leave their posts even as they decried O’Keefe’s tactics.

In the new civil lawsuit filed in U.S. District Court in Washington Thursday, Creamer, his Strategic Consulting Group and a related firm called Democracy Partners accuse O’Keefe and several colleagues of conspiring to violate federal and District of Columbia laws against the secret recording of private conversations.
