The Republican National Convention edited an audio clip of Solicitor General Donald Verrilli to make it sound like he was at a loss of words to defend the Affordable Care Act during his oral arguments to the U.S. Supreme Court.

In a 30-second ad released by the RNC late Tuesday, Verrilli stutters and awkwardly pauses before trailing off.

“For more than 80 percent of Americans, the ah insurance system does provide effective access -- Excuse me. Ah -- it ah be-be because the ah the ah the -- Excuse me,” he says in the ad.

As he finishes, the ad displays the words: “ObamaCare. It’s a tough sell.”

However, when Bloomberg compared the ad to the actual audio recording of Verrilli's argument before the justices, they found that it had been doctored.

“For more than 80 percent of Americans, the, ah, insurance system does provide effective access,” Verrilli actually said, pausing briefly. “Excuse me, but for more than 40 million who do not have access to health insurance, either through their employer or through government programs such as Medicare or Medicaid, the system does not work.”
