U.S. President Joe Biden honored Feinstein in video remarks as a defender of American values and a dear friend at a memorial service for the late U.S. senator.
California Sen. Dianne Feinstein suffered complications from shingles that included Ramsay Hunt syndrome and encephalitis, or inflammation of the brain, her office confirmed on Thursday.
Questions continue to swirl around Sen. Dianne Feinstein and her mental capacity to serve in the Senate.
In a statement released Wednesday, Feinstein, who was using a wheelchair as she returned to the Capitol, said she is "prepared to resume my duties in the Senate," but with a "lighter schedule" as she continues her recovery.
Feinstein, 89, was hospitalized in February with a case of shingles. She was released in early March and had been continuing her recovery at home.
A small but growing number of Democrats are calling for Sen. Feinstein to resign from the Senate arguing her absence is stalling the confirmation of President Biden's judicial nominees.
