Dianne Feinstein, a long-serving Democratic U.S. senator from California and gun control advocate who spearheaded the first federal assault weapons ban and documented the CIA's torture of foreign terrorism suspects, has died at 90, a source familiar with the news said Friday.
Feinstein's office did not immediately respond to a request for comment on the news, first reported by the Punchbowl news outlet.
Feinstein was a Washington trail-blazer who among other accomplishments became the first woman to head the influential Senate Intelligence Committee.
