Accused Russian agent Maria Butina had wider high-level contacts in Washington than previously known, taking part in 2015 meetings between a visiting Russian official and two senior officials at the U.S. Federal Reserve and Treasury Department.

The meetings, revealed by several people familiar with the sessions and a report from a Washington think tank that arranged them, involved Stanley Fischer, Fed vice chairman at the time, and Nathan Sheets, then Treasury undersecretary for international affairs.

Butina traveled to the United States in April 2015 with Alexander Torshin, then the Russian Central Bank deputy governor, and they took part in separate meetings with Fischer and Sheets to discuss U.S.-Russian economic relations during Democratic former President Barack Obama's administration.
