U.S. Sen. Dianne Feinstein has died, sending the nation into mourning.
February was a turbulent month for the senator.
Despite her health struggles, the politician was determined to return to office.
Her return to work was met with a palpable wariness from those around her.
Her rapidly diminishing health was evident; she was escorted around in a wheelchair and seemed frail.
Although the encephalitis was claimed to have been resolved, Feinstein continued to have trouble with Ramsay Hunt syndrome.
