Bozeman native Michael McFaul was sworn in as ambassador to Russia by Secretary of State Hillary Clinton on Tuesday afternoon.

The ceremony at the state department in Washington, D.C., came less than a month after the Senate confirmed McFaul’s appointment to the post. The 1981 Bozeman High grad waited more than three months for the Senate to confirm his appointment after President Barack Obama nominated him.

McFaul, 47, has served as the president’s top Russian expert, designing the administration’s policy to “reset” relations with Moscow. McFaul is the first non-diplomat in three decades to serve as the chief U.S. representative to Moscow, the Washington Post has reported.
