Texas Governor Rick Perry has no love for nameless allegations.
When Politico reporter Mike Allen asked him about rumors of discontentment within his campaign Tuesday morning in Iowa, Perry repeatedly insisted that Allen name his source before he'd comment on the story.
"I don't know who you're talking to so I can respond to," he said. "Give me a name."
When Allen would not name his source and instead repeated the question, Perry dug in.
"You've got a name?" he asked. "You've got a name? You've got a name?"
He added: "If you don't have a name to tell me this individual said this, then I don't take as a corroborative source. Don't come to me and say respond to this, and you're either not willing or you don't have a name."
