Newsom [was] corporate counsel and a board member for Trans-International Computer Investment Corporation (TCI), which handled classified government contracts, for which Newsom was issued a National Security Clearance. TCI went bankrupt in 1971 after what the Sacramento District Attorney called "the biggest stock fraud in California history".

For most of 1969 and 1970, Newsom traveled across Europe alongside former SS security service member Otto von Bolschwing who had been brought to the U.S. by the CIA under Operation Paperclip and appointed TCI's president by Getty due to his former Nazi intelligence connections and their value in obtaining defense technology contracts. Newsom referred to von Bolschwing as "suave", "plausible", and "world weary".

Newsom made his fortune via the Getty family.

Investment management

Newsom served as a financial advisor for the Getty family businesses. He directly managed the Gordon P. Getty Family Trust, which is estimated at more than $2 billion. The trust earns about 2 percent a year resulting in approximately $40 million in annual income. He screened potential investments and made recommendations on real estate, stocks, bonds, and other ventures. "I make my living working for Gordon Getty", Newsom said in 2003.
