REMEMBERING THE LEGACY OF SEN. DIANNE FEINSTEIN
"Senator Feinstein never backed away from a fight for what was just and right. At the same time, she was always willing to work with anyone, even those she disagreed with, if it meant bettering the lives of Californians or the betterment of our nation," he added.
"There are few women who can be called senator, chairman, mayor, wife, mom and grandmother. Senator Feinstein was a force of nature who made an incredible impact on our country and her home state.
