Former Vice President Kamala Harris, before a theater full of supporters in Los Angeles, struck a tone of hope, saying that although the present time may seem dark for those gathered, it’s important to continue fighting for a better America. “Know times like this require us to fight fire with fire,” the former vice president added. The Los Angeles event was the third stop in her multi-city tour to promote her book, “107 Days,” which was released last week. The former vice president, who in July announced she would not mount a bid to become California’s next governor, did not offer specifics about her future plans. She’s scheduled to speak again at The Wiltern in Los Angeles on Oct. 28.
