Marina Butina, the Russian woman accused of cozying up to conservatives in the lead-up to the 2016 U.S. election, pleaded guilty Thursday to conspiring to work as a Russian agent as details of her cooperation were unveiled in Washington, D.C., federal court.

Butina admitted to working in the U.S. on behalf of the Russian government without notifying the Justice Department. She admitted she worked at the behest of a Russian official—believed to be Alexander Torshin, the Russian central bank's deputy governor—as she sought to infiltrate Republican political circles, including the National Rifle Association.

Court documents show that during that time, she worked alongside and was romantically involved with a man believed to be Paul Erickson, a Republican operative with ties to the NRA. Neither Torshin nor Erickson have been identified by name in court papers or proceedings.
