Feinstein, Under Pressure to Resign, Asks to Step Down From Judiciary Panel

WASHINGTON — Senator Dianne Feinstein on Wednesday pushed back on calls for her resignation but asked to step away from the Judiciary Committee indefinitely while recovering from shingles, responding to mounting pressure from Democrats who have publicly vented concerns that she is unable to perform her job.

Ms. Feinstein, an 89-year-old California Democrat, has been away from the Senate since February, when she was diagnosed with the infection. Her absence has become a problem for Senate Democrats, limiting their ability to move forward with judicial nominations. In recent days, as it became clear she was not planning to return after a two-week recess, pressure began to increase for Ms. Feinstein to resign.

On Wednesday night, she said she would not do so, but offered a stopgap solution, saying she would request a temporary replacement on the panel.
