Republican political pollster Chris Wilson is aware of incidents in which Herman Cain allegedly sexually harassed a woman at the National Restaurant Association “a couple of times” during the 1990s, he said this morning on an Oklahoma radio station.

Wilson, a Rick Perry supporter and pollster for the SuperPAC that supports Perry, said on the radio station KTOK that the woman was a young employee at the NRA and the incidents occurred at a restaurant in Crystal City, Va.

It was “only a matter of time” before these allegations came out, because others at the NRA also knew about the alleged harassment, he said.

Wilson maintained that everyone at “the campaign” knew about the incidents and the woman’s departure from the NRA — though he did not specify which campaign he was referring to.

In the past week, Cain has been pegged with three accusations of sexual harassment from women associated with the NRA.

But Wilson said he had nothing to do with the leak.

“To be clear, and you can ask any of the reporters covering this story,  I had nothing to do with leaking this in any way, and I’ve never discussed or shared this story with any of my clients – period,” he said in a statement.

In the meantime, a radio host in Iowa, Steve Deace, told Politico in an email that Cain made uncomfortable and suggestive comments to female employees. What’s his standard?

“For example, I wouldn’t tell them or any other woman I am not married to nor related to how pretty she is,” Deace said.

This is the first such allegation against Cain not related to the NRA.
