Senator Dianne Feinstein, California's longest-serving woman in the Senate, has passed away at the age of 90.

Feinstein was first elected in 1992 and was known for her advocacy of gun control measures.

She served as San Francisco's mayor during a challenging period, including the aftermath of two political assassinations in 1978.

Feinstein faced a recall effort during her tenure as mayor but was reelected due to her moderate governing style.

Her political upbringing was shaped by her parents' differing political affiliations.

Feinstein's national prominence grew during the AIDS epidemic, where she led San Francisco's efforts to combat the disease.

She won a Senate seat in 1992 and became part of the "Year of the Woman."

Feinstein championed gun control and played a significant role in passing a federal assault weapons ban in 1994.

In 2014, she released a report on CIA torture practices, holding the intelligence community accountable.

Despite some controversy and health concerns in later years, Feinstein remained an influential figure in American politics.
