President Joe Biden and other political leaders in the country have given their respects and tribute to U.S. Sen. Dianne Feinstein, who died at the age of 90.

The longest-serving woman senator in U.S. history and San Francisco’s first female mayor passed away at her home in Washington, D.C., her office confirmed Friday morning.

Biden called Feinstein “a true trailblazer and a cherished friend.”

“In San Francisco, she showed enormous poise and courage in the wake of tragedy, and became a powerful voice for American values. Serving in the Senate together for more than 15 years, I had a front row seat to what Dianne was able to accomplish,” the president said in a statement.

“Often the only woman in the room, Dianne was a role model for so many Americans — a job she took seriously by mentoring countless public servants, many of whom now serve in my Administration. She had an immense impact on younger female leaders for whom she generously opened doors. Dianne was tough, sharp, always prepared, and never pulled a punch, but she was also a kind and loyal friend, and that’s what (First Lady) Jill and I will miss the most,” Biden said.

For California Gov. Gavin Newsom, Feinstein was 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,” Newsom said. “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.”
