During the White House Press Briefing today, Press Secretary Jay Carney told a reporter to “be mindful of your sources” when asked about the Drudge Report article reporting that Mitt Romney was considering selecting former Army General and current CIA Director David Petraeus as his running mate.

The report asserted that President Obama privately told a top fundraiser that Romney was considering it.

“I can say with absolute confidence, such an assertion has never been uttered by the president.” Carney said. “And again be mindful of your sources.”
