Not related, close friends with one of the sons and family - the Gettys consider Newson “another son” and bankrolled some of his lefty activities.
“Gordon Getty provided critical seed money for Newsom’s early ventures, investing in 10 of his first 11 businesses, including the PlumpJack hospitality group. This financial patronage fueled Newsom’s transition from entrepreneur to politician.”
Yes i remembered it wrong. Looked it up later. Very close friendship relationship!
