Calls for Sen. Feinstein's resignation grow amid concerns over her Senate attendance.

Multiple Democrats close to Senator Dianne Feinstein are concerned that she may never return to the Senate due to her shingles diagnosis, which has kept her away from the Capitol for nearly two months. Her absence has already forced her party to change how they run the Senate, where Democrats can’t move President Joe Biden’s judicial picks without her vote. The emerging race to succeed Feinstein is in a holding pattern of its own thanks to the uncertainty about her future.
