President Obama's campaign beat back questions from reporters today about why the incumbent's Thursday night convention speech is being moved from Charlotte's Bank of America stadium indoors to the smaller Time Warner Cable Arena. 

The decision was made "on the staff level," campaign spokeswoman Jen Psaki  said. "This is not a Panthers game, as you may know. It's a national special security event. So the criteria used for that is ensuring that we're not putting the public safety or security of anybody in the audience at risk."

Asked if lack of interest was the real reason for the move -- as Republicans have suggested -- Psaki was emphatic. 

“Absolutely not," he said. "[W]hen you had 65,000 ticketed people and 19,000 on the waiting list, our concern was more about turning people away than filling the stadium.”
