Obama / Boston Update

President Barack Obama says he's confident the government's anti-terror complex did what it was supposed to before the Boston Marathon bombings. But he's asked a group of four inspectors general to launch a 90-day review. They'll look at whether information sharing was adequate. And if there's something the government could have done to prevent the Patriot's Day attack. The review is headed by Charles McCullough, the I.G. of the intelligence community. He'll be joined by the inspectors general of the CIA, Justice and Homeland Security.
