Esther Ferris, the mother of Fox News host Judge Jeanine Pirro, has passed away at 90 from pancreatic cancer. "She was my muse, my hero," Judge Pirro said of her mother, who served as an inspiration in her career as both a Prosecutor and Judge. "I have lost my best friend. My mother stood up for the victim, for the abused, before it was vogue. She was a great influence on me and everyone around her. She took care of the people who couldn't take care of themselves."
