A gun control group founded by New York City Mayor Michael Bloomberg is airing a Super Bowl ad calling for background checks.
   
The 30-second spot by Mayors Against Illegal Guns will air in the Washington area during today's game between the Baltimore Ravens and San Francisco 49ers.
   
It urges lawmakers to pass rules requiring background checks on guns.
   
The ad is  narrated by children, with ``America the Beautiful'' playing in the background.
  
It includes decades-old footage of National Rifle Association Executive Vice President Wayne LaPierre saying the gun lobby group approves of the checks.
   
LaPierre recently testified before the Senate Judiciary Committee that the N-R-A no longer supports background checks for all gun sales.
   
Mayors Against Illegal Guns is a coalition of more than 900 mayors from 48 states.
