WASHINGTON—Having been alive as far back as 1933, Sen. Dianne Feinstein of California, a trailblazer in being old, died Thursday night at age 90. “Sen. Feinstein, born Dianne Goldman, started off young but through hard work and dedication rose through the ranks to become very, very old,” said the late Democrat’s chief of staff, James Sauls, who in prepared remarks to reporters cited Feinstein’s many career highlights, such as turning 88 years old in 2021, turning 89 years old in 2022, and, just this year, turning 90. “Her remarkable persistence as the oldest sitting U.S. senator made her a role model to nonagenarians everywhere. Across the nation tonight, little girls will find inspiration in her story, knowing that they, too, can one day grow up to be incredibly old.” Sauls added that while Feinstein did not fulfill her longtime goal of clinging to power in the Senate as long as her late mentor in aging, the 100-year-old Strom Thurmond, she nonetheless spent her final years shattering expectations for what an unbelievably infirm and exhausted person can and should do.
