Asked by CNN if Christie had been invited to appear at the event in Morrisville, a suburb of Philadelphia, Palatucci told CNN, "No."

The report came a few days after Christie toured some of the hardest-hit parts of his state with President Obama. Palatucci added to CNN that the Romney campaign "knew better than to ask, given the situation here."

Christie shrugged off suggestions that the appearance would hurt Romney's chances of being elected president.

"I have no idea, nor am I the least bit concerned or interested," Christie said about a week earlier. "I've got a job to do here in New Jersey that's much bigger than presidential politics, and I could care less about any of that stuff."
