Last October, two weeks before the midterm elections, a budding model named Jeff Thomas walked into the Polo Lounge at the Beverly Hills Hotel for lunch with a friend who had been working with a well-connected Democratic political operative named Jack Bury. Thomas, then 35, dabbled in real estate, the art world, and the inchoate realm of social media influencing. But his most relevant avocation was as a former boyfriend of Peter Thiel, the multi-billionaire entrepreneur and Republican mega-donor. Thomas, who first met Thiel at Coachella in 2015, lived near the hotel at a $13 million place in the Hills that Thiel had underwritten.
