More signs that former mayor Adrian Fenty is moving to the West Coast: Tuesday’s announcement that he’s joined Perkins Coie’s Silicon Valley law office, where he’ll work in the business development department. (Nice gig: the firm represents Amazon, Microsoft, Google, Facebook and Twitter.) Fenty is keeping his job at Andreessen Horowitz, a hot Silicon Valley venture capital shop, and told the Silicon Beat blog that he’ll spend weekdays in California and come to D.C. on weekends to see his kids. House shopping? No. Fenty told the blog that he’ll be staying with a “friend” in Palo Alto, but declined to comment on “anything involving my social life.” Perhaps the friend is Laurene Powell Jobs, the widow of Steve Jobs — and as we reported last month, Fenty’s new girlfriend.
