U.S. Sen. Dianne Feinstein died at age 90 on Thursday night at her home in Washington, D.C., her office said Friday.
Feinstein, who was born and raised in San Francisco, had served in the Senate since 1992. She was a trailblazer, entering the office with a number of other women who advocated for liberal causes. Feinstein was also known for her pragmatism, which could reach across the aisle.
A hallmark of Feinstein's political career was when she was thrust into the mayor's office in 1978, when San Francisco Mayor George Moscone and Supervisor Harvey Milk were killed at City Hall by former Supervisor Dan White. Feinstein, who was president of the Board of Supervisors, automatically succeeded Moscone.
