(WHTM) — Following the death of California Democratic Sen. Dianne Feinstein, Pennsylvania Sen. John Fetterman released a statement issuing his condolences.

“Senator Feinstein was a true trailblazer in American politics who led on issues like gun violence prevention and LGBTQ rights,” Fetterman said. “Gisele and I send our deepest condolences to her family, staff, and loved ones in this difficult time.”

Fetterman is among a number of politicians who are responding to the news of Feinstein’s death.

Senate Majority Leader Chuck Schumer (D-N.Y.) called Feinstein “[a] legend in the Senate” and California Governor Gavin Newsom called the late senator a “political giant” in the following tweet posted to X, formerly Twitter.

“Dianne Feinstein was many things — a powerful, trailblazing U.S. Senator; an early voice for gun control; a leader in times of tragedy and chaos. But to me, she was a dear friend, a lifelong mentor, and a role model not only for me, but to my wife and daughters for what a powerful, effective leader looks like.

She was a political giant, whose tenacity was matched by her grace. She broke down barriers and glass ceilings, but never lost her belief in the spirit of political cooperation. And she was a fighter — for the city, the state and the country she loved. Every race she won, she made history, but her story wasn’t just about being the first woman in a particular political office, it was what she did for California, and for America, with that power once she earned it. That’s what she should be remembered for.

There is simply nobody who possessed the strength, gravitas, and fierceness of Dianne Feinstein. Jennifer and I are deeply saddened by her passing, and we will mourn with her family in this difficult time.”
