Dianne Feinstein dies at 90

Dianne Feinstein, the oldest member of the U.S. Senate and the longest-serving senator from California, has died at age 90, two sources familiar with the matter told NBC News on Friday.

The Democrat’s passing marks the end of a boundary-pushing political career that spanned more than half a century, studded with major legislative achievements on issues including gun control and the environment.

Feinstein had planned to retire at the end of her current term in 2024.

Feinstein’s death leaves vacant her powerful Senate seat, requiring Gov. Gavin Newsom to appoint a temporary successor.

A San Francisco native, Feinstein cleared a path for women in politics as she rose the ranks of leadership. After two failed bids for mayor, she was elected president of San Francisco’s board of supervisors in 1978, becoming the first woman to hold the title.
