Dianne Feinstein's Health Concerns Spark Controversy in Senate.

Senator Dianne Feinstein, 89, returned to the Senate after several months at home in San Francisco with shingles and complications from Ramsay Hunt syndrome, which caused partial paralysis and a drooping eyelid and face. She has also had a case of encephalitis, a swelling of the brain, which can cause memory loss and other effects. Despite her health issues, Feinstein continues to vote and speak up in committee hearings. Her presence in the Senate is essential for Democrats to pursue their agenda, including confirming judges, while maintaining maximum leverage.
