“Face the Nation” producers noticed something funny during Sunday’s show: a Mitt Romney for President ad that aired during the broadcast and included host Bob Schieffer.

“It is my understanding that just a few minutes ago, the Romney campaign bought time on ‘Face the Nation’ during one of our commercial blocks,” said Schieffer as he began a discussion with his panel.

“I am running this not to give circulation to it but just to state that, obviously, I have no connection with the Romney campaign. This was done without our permission. It comes as a total surprise to me, and that is that,” said Schieffer. “But that is – that’s where we are in politics.”
