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 conspiring to work in the U.S. on behalf of the Russian government without notifying the Justice Department. She, along with an American citizen, 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 and influence conservative political circles.
