Super Bowl security prepared
Washington - President Barack Obama's counter terrorism advisor says he's not aware of any credible terrorist threats against the Super Bowl.
John Brennan says officials are "very comfortable" with the security measures in place for Sunday night's National Football League championship game in Miami between the New Orleans Saints and the Indianapolis Colts.
Fans aren't going to be allowed to bring large bags into the Super Bowl stadium. Also, there will be 100 magnetometers - like those in use at airports - to detect metal objects.
Other measures include radiological, biological and chemical weapon detection and protection devices. And nearly everyone entering the stadium will be subjected to a pat-down search.
Brennan spoke on NBC television's Meet the Press.
