BURNETT: "Meantime tonight, another big thing for the president beyond meeting the pope in Rome was big news on ObamaCare. The White House announcing more than 6 million people have signed up for it. Only 1 million shy of the administration's initial goal but beating revised targets. Now of course, after the botched rollout of the web site in October, expectations came way down. This is a big positive surprise as the president's made a big push for people to sign up. As we've been reporting, young adults are key to keeping insurance costs down."
