Sen. Dianne Feinstein, D-Calif., is returning to work in Washington, D.C., on Wednesday after a prolonged absence as she recovered from shingles, a spokesperson confirmed to Spectrum News.

Her time away from the upper chamber led to calls for her to resign from some Democrats, and at least one Republican presidential candidate.

“I’m glad that my friend Dianne is back in the Senate and ready to roll up her sleeves and get to work," Senate Majority Leader Chuck Schumer, D-N.Y., said in a statement. "After talking with her multiple times over the past few weeks, it’s clear she’s back where she wants to be and ready to deliver for California.”

Feinstein, 89, has not been in the Senate since February, leaving Democrats without the majority they need on the Judiciary Committee to confirm President Joe Biden's judicial nominees. The California Democrat asked to be temporarily replaced on the committee by a Democrat, but Republicans were needed to approve the move and they declined to do so.

Feinstein has come under increasing pressure to resign or step down from her duties. While she has defended her effectiveness, she has faced questions in recent years about her cognitive health and memory, and has appeared increasingly frail.

In 2020, she said she would not serve as the top Democrat on the judiciary panel after criticism from liberals about her handling of Justice Amy Coney Barrett’s confirmation. Earlier this year, she said she would not serve as the Senate president pro tempore, or the most senior member of the majority party, even though she was in line to do so. The president pro tempore opens the Senate every day and holds other ceremonial duties.

Rep. Ro Khanna, D-Calif., called on her to resign from the Senate during her absence, saying it was “unacceptable” for her to miss votes to confirm judges who could be weighing in on abortion rights, a key Democratic priority.

Another member of the California delegation, Democratic Rep. Pete Aguilar, said last month that Feinstein is “a legend in California politics and a legend in the Senate chamber” but that her vote will be needed as Congress tries to figure out how to raise the debt ceiling this year.
