"Ms. Tauscher resigned her House seat on June 26, 2009, when she was confirmed by the Senate as under secretary of state for arms control and international security, a post to which she was appointed by Secretary of State Hillary Clinton. Ms. Tauscher played a key role in achieving the New Strategic Arms Reduction Treaty of 2010, which placed limits on bombers, launchers and submarines as well as nuclear warheads. The treaty, which expires in 2021, sent American and Russian nuclear arsenals to their lowest levels in nearly 60 years. She served as under secretary until 2012."
