When he emerged from his motorcade at the top of the Oval in jeans, no necktie and a casual blue jacket, Russian President DMITRY MEDVEDEV was a striking contrast to those who had come to greet him. Provost JOHN ETCHEMENDY wore a dark dress suit and tie, and former Secretary of State CONDOLEEZZA RICE, political science professor and Hoover Institution senior fellow, had on an off-white pants suit and pearls. Medvedev, who had spent the morning visiting Apple, Cisco, Twitter and Yandex Labs, casually remarked that he was a bit underdressed, to which Rice replied: “It’s a college campus. It’s California. You’re dressed perfectly.”
