Washington (CNN) front page — On Monday, President Obama singled Naif al-Mutawa out for special praise for promoting international understanding with his “The 99″ comics”.

“His comic books have captured the imagination of so many young people with superheroes who embody the teachings and tolerance of Islam,” Obama said.

And on Tuesday, Mutawa was treated like a rock star at the president’s Summit on Entrepreneurship, with people lining up to get his flashy, superhero-embossed business cards and polite words of encouragement.
