Republican Senator Pat Roberts’ re-election campaign has posted an online ad attacking independent candidate Greg Orman as a liberal pretending to be conservative.

But Orman’s campaign demanded Friday that Roberts’ team remove the ad because it edits audio from their recent debate at the Kansas State Fair.

The ad accuses Orman of pretending to be conservative like Roberts. It features a string of video clips from the debate in which Orman agrees with Roberts.

The last of those clips features audio edited from two parts of the debate. Orman spokesman Sam Edelen called the audio “fake” and said it had been manipulated while being represented as exactly what Orman said at the debate.

Roberts campaign manager Corry Bliss called the criticism laughable.
