The U.S. Department of Justice unveiled on Monday the arrest and criminal complaint against a Russian woman charged with conspiring against the United States as an undisclosed agent of the Russian Federation.

The woman is identified as Maria Butina, a 29-year-old Russian citizen who has been living in the United States on a student visa since 2016. Between 2015 and 2017, she worked for a “high-level official in the Russian government,” according to the Justice Department. Together, she and the official were accused of “developing relationships with U.S. persons and infiltrating organizations having influence in American politics,” to advance Russian interests.
