A Russian woman who tried to ingratiate herself with American political conservatives ahead of the 2016 election was sentenced on Friday to 18 months in prison by a federal judge.

Maria Butina was sentenced by  Judge Tanya Chutkan of the U.S. District Court for the District of Columbia on a single count that she conspired to act as an unregistered Russian agent. Butina pleaded guilty in December in exchange for federal prosecutors dropping a second charge against her.
