Dianne Feinstein, Pioneering Senator and San Francisco's First Female Mayor, Dies at 90

Sen. Dianne Feinstein, the longest serving woman in the Senate, died at age 90. She was first elected to the Senate from California in 1992.

Feinstein served as mayor of San Francisco from 1978-1988, leading the city after the assassinations of Mayor Moscone and Supervisor Milk.

As senator, Feinstein advocated for gun control, passing an assault weapons ban in 1994. She also released a report on CIA torture post 9/11.

Feinstein was known as a moderate who believed in political cooperation. She remained in office into her late 80s, to some Democrats' frustration.

Feinstein's legacy includes breaking barriers for women in politics as San Francisco's first female mayor. She inspired other women to pursue leadership roles.
