In Andrew Brietbart’s 2011 book “Righteous Indignation,” which is part biography, part screed against a liberal media elite, the late entrepreneur and political commentator recalled taking tennis lessons in Los Angeles with his childhood friend Laurence Solov.

Breitbart described taking cover with Solov as Arnold Schwarzenegger—the future Republican governor of California who shared a tennis coach with the pair—took delight in “literally terrorizing me and my best friend … by hitting ball after ball as hard as he could at us, to the point where we wailed in the corner and he cackled aloud.”
