Dianne Feinstein, Longest-Serving Female Senator and San Francisco Political Icon, Dies at 90

Dianne Feinstein, the longest-serving female senator, died at age 90. She was a centrist Democrat who championed gun control and intelligence oversight.

Feinstein became San Francisco's mayor in 1978 after Mayor George Moscone and Supervisor Harvey Milk were assassinated. She served as mayor for 9 years.

In the Senate, Feinstein helped pass an assault weapons ban and led an investigation into CIA interrogation techniques post 9/11.

As the top Democrat on the Judiciary Committee, she questioned Supreme Court nominees but supported many conservative judicial picks.

Feinstein faced increasing pressure to resign amid health issues, but she resisted calls to step down before finishing her term.
