(CNN) -- Saif al-Islam Gadhafi, 38, has never lived a day in which his father Moammar didn't rule Libya -- as its undisputed leader inside the country and an enigmatic, controversial voice for the world. And yet, as the Libyan government faced a stiff popular uprising, it was Moammar Gadhafi's second eldest son -- and not the Leader of the Revolution himself -- who was first to talk to the nation about the unrest and detail a plan to address it. The speech, made early Monday on Libyan state television, does not mean that Saif Gadhafi has usurped power from his father: Senior U.S. officials said there's no indication the elder Gadhafi is losing his grip.
