I know it's a wiki…
but it mentions Getty (California mafia family) and Willie Brown….
Newsom graduated from Santa Clara University in 1989. Afterward, he founded the boutique winery PlumpJack Group with billionaire heir and family friend Gordon Getty as an investor. The company grew to manage 23 businesses, including wineries, restaurants, and hotels. Newsom began his political career in 1996, when San Francisco mayor Willie Brown appointed him to the city's Parking and Traffic Commission.[1] Brown then appointed Newsom to fill a vacancy on the Board of Supervisors the next year and Newsom was first elected to the board in 1998.
