Pawlenty clarifies Bachmann jab

(CNN) - Republican presidential candidate Tim Pawlenty walked back earlier criticism of rival Michele Bachmann's migraines on Wednesday, calling the attention over her headaches "a sideshow."

"I think it's mostly a sideshow," Pawlenty said on Fox News. "I've observed Congresswoman Bachmann. I've never seen her have a medical condition or impairment that would seem to be a concern."
