Senator Dianne Feinstein, the oldest member of Congress, died at the age of 90 after months of declining health. She had a long career as the first woman to serve as mayor of San Francisco and the first woman to represent California in the U.S. Senate. Feinstein held many leadership positions over her 30 years in the Senate, including as chair of the Senate Rules Committee and Senate Judiciary Committee. She played a key role in passing the 1994 Federal Assault Weapons Ban. The document outlines Feinstein’s political career from her start in local politics in San Francisco in the 1960s through her time in the Senate. It highlights her role in investigating the CIA’s detention and interrogation program after 9/11 and releasing the Senate torture report in 2014. During her later Senate career, Feinstein faced some criticism over her handling of Supreme Court confirmation hearings.

She remained active in the Senate until near the end of her life.
