San Jose Mayor Matt Mahan on Thursday announced he’s joining the crowded race for California governor, casting himself as a moderate Democrat with a track record of tackling some of the state’s most persistent issues including homelessness and crime. Mahan also criticized Newsom’s focus on President Donald Trump and the governor’s social media trolling in an op-ed last year. He was classmates with Mark Zuckerberg, who Mahan said persuaded him to go into tech instead of law school. Mahan in recent months also hosted a number of gubernatorial candidates in San Jose, but said no one has impressed him. He often joins weekend clean-up efforts along San Jose waterways and city parks.
