WASHINGTON (AP) — President Barack Obama's counterterrorism adviser 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 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's "Meet the Press."
