“Herman Cain has never sexually harassed anybody, period. End of story.” Block said in an interview on MSBNC Monday morning. “The only people who spoke publicly about the story in the article are the ones who are in the best position to know. They are the chair, the vice chair, and immediate past chair of the National Restaurant Association during Herman Cain’s tenure. And all three said that he was a man of total integrity. Every negative word and accusation in the article is sourced to a series of unnamed or anonymous sources and this is questionable at best.”

Politico on Sunday night published a story, based on a review of documents, that reports that two women were given five-figure financial settlements and left the association after complaining of sexually inappropriate comments allegedly made by Cain.

Block said that he was “not personally aware of any cash settlement related to sexual harassment charges to Mr. Cain.”

“He said to me, ‘When there are facts, bring them to me. Let me face my accusers and we will deal with this.’”

Cain is scheduled to give an address at the National Press Club at noon, and he will sit down for an interview at 11:20 on Fox News.

Cain declined to speak to reporters prior to his appearance at the American Enterprise Institute Monday morning. He stepped out of his black Suburban at 9 a.m. and muttered a quiet “good morning” to gathered reporters before slipping into a side door. During much of his speech, he steered cleared of the subject, detailing his 9-9-9 plan instead. When a questioner raised the issue, Cain said he was going to stick to his topic and that he would take his arrows later.

Before walking off the stage, he got folksy and said:

“By the way folks, yes I am an unconventional candidate, and yes, I do have a sense of humor. Some people have a problem with that,” he said. “But to quote my chief of staff and all of the people that I’ve talked to around this country, Herman, be Herman. And Herman is going to stay Herman.”
