Donald Trump’s campaign manager, Corey Lewandowski, said in a radio interview on Tuesday that Ted Cruz’s campaign was not involved in an attack ad on Trump’s wife, Melania. Lewandowski’s comments contradict his own candidate’s repeated claims the Cruz campaign was responsible.

Lewandowski made the comments on the John Fredericks Show, where he denied the Trump campaign had any involvement with a National Enquirer story alleging Cruz had affairs with five different women. Roger Stone, a long time Trump aide who is no longer affiliated with the campaign, was quoted in the story.

“I have no control over what Roger Stone does, doesn’t work for the campaign. He’s an independent individual who has no relationship with the campaign in any way, shape, or form,” said Lewandowski. “For them to intimate otherwise is completely inaccurate and it’s a narrative that they want to continue to perpetuate. The bottom line is Roger Stone is as much tied to this campaign as the super PAC that leaked that is tied to the Cruz campaign.”
