The women complained of sexually suggestive behavior by Cain that made them angry and uncomfortable, the sources said, and they signed agreements with the restaurant group that gave them financial payouts to leave the association. The agreements also included language that bars the women from talking about their departures.

In a series of comments over the past 10 days, Cain and his campaign repeatedly declined to respond directly about whether he ever faced allegations of sexual harassment at the restaurant association. They have also declined to address questions about specific reporting confirming that there were financial settlements in two cases in which women leveled complaints.

POLITICO has confirmed the identities of the two female restaurant association employees who complained about Cain but, for privacy concerns, is not publishing their names.

Cain spokesman J.D. Gordon told POLITICO the candidate indicated to campaign officials that he was “vaguely familiar” with the charges and that the restaurant association’s general counsel had resolved the matter.

The latest statement came from Cain himself. In a tense sidewalk encounter Sunday morning outside the Washington bureau of CBS News — where the Republican contender had just completed an interview on “Face the Nation” — Cain evaded a series of questions about sexual harassment allegations.

Cain said he has “had thousands of people working for me” at different businesses over the years and could not comment “until I see some facts or some concrete evidence.” His campaign staff was given the name of one woman who complained last week, and it was repeated to Cain on Sunday. He responded, “I am not going to comment on that.”

He was then asked, “Have you ever been accused, sir, in your life of harassment by a woman?”

He breathed audibly, glared at the reporter and stayed silent for several seconds. After the question was repeated three times, he responded by asking the reporter, “Have you ever been accused of sexual harassment?”

Cain was president and CEO of the National Restaurant Association from late 1996 to mid-1999. POLITICO learned of the allegations against him, and over the course of several weeks, has put together accounts of what happened by talking to a lengthy roster of former board members, current and past staff and others familiar with the workings of the trade group at the time Cain was there.

In one case, POLITICO has seen documentation describing the allegations and showing that the restaurant association formally resolved the matter. Both women received separation packages that were in the five-figure range.

On the details of Cain’s allegedly inappropriate behavior with the two women, POLITICO has a half-dozen sources shedding light on different aspects of the complaints.

The sources — including the recollections of close associates and other documentation — describe episodes that left the women upset and offended. These incidents include conversations allegedly filled with innuendo or personal questions of a sexually suggestive nature, taking place at hotels during conferences, at other officially sanctioned restaurant association events and at the association’s offices. There were also descriptions of physical gestures that were not overtly sexual but that made women who experienced or witnessed them uncomfortable and that they regarded as improper in a professional relationship.

Peter Kilgore, who was the association’s general counsel in the 1990s, and remains in that position today, has declined to comment to POLITICO on whether any settlements existed, saying he cannot discuss personnel matters.

But one source closely familiar with Cain’s tenure in Washington confirmed that the claims related to allegations of sexual harassment — behavior that disturbed members of the board who became aware of it, as well as the source, who otherwise liked Cain.

“I happen to know there were sealed settlements reached in the plural. I think that anybody who thinks this was a one-time, one-person transgression would be mistaken,” this source said.

The first woman was identified to POLITICO by a former association board member, and her identity was confirmed by two additional sources.

The former board member recalled learning of the woman’s departure at a 1999 association board meeting and trade expo in Chicago.

“She was offered a financial package to leave the association, and she did,” said the former board member. “What I took offense at was that it was clear that rather than deal with the issue, there was an effort to hush it up. She was offered a way out to keep quiet.”

A second source with close ties to the restaurant association from that period said the woman revealed at the time that she had suffered what the source described as “an unwanted sexual advance” from Cain at a hotel where an event involving the group was taking place.

A third source said the woman has indicated to her current employer that she received a compensation package from the association and has warned the employer that she might be the subject of an embarrassing story involving a presidential candidate.

The second woman’s identity was confirmed by a source familiar with the association.

On Oct. 20, POLITICO first approached Gordon, who serves as the campaign’s vice president for communications, about whether Cain had been the subject of complaints of sexual harassment.

After not responding to the question for several days, Gordon emailed POLITICO on Oct. 24 that any dispute about Cain’s conduct at the restaurant association “was settled amicably among all parties many years ago.”

“These are old and tired allegations that never stood up to the facts,” Gordon wrote in an email response. “This was settled amicably among all parties many years ago, and dredging this up now is merely part of a smear campaign meant to discredit a true patriot who is shaking up the political status quo.”

Gordon added: “Since critics haven’t had much luck in attacking Mr. Cain’s ideas, they are trying to attack him personally.”

On Wednesday, the response shifted. Gordon telephoned to assert he was not using “settled” in a legal context but rather simply meant the matter was “resolved.”

In that interview, Gordon told POLITICO he had spoken to Cain about the allegations and said Cain was “vaguely familiar” with the situation.

“He was vaguely familiar with it and wanted me to get with the [National Restaurant Association] lawyer who worked the case, Peter Kilgore. He said, ‘Just get with Peter Kilgore at the NRA.’ He remembered there was something vaguely, some allegation, but he wasn’t familiar with it. Our lawyer called Peter Kilgore. Their policy is they don’t discuss personnel. That’s what our lawyer then told me.”

Added Gordon: “When you’re in a leadership position, sometimes people just try to take a shot at you.”

As to whether the association under Cain ever paid a monetary settlement to women who had leveled such accusations against him, Gordon referred the question to the restaurant trade group.

Kilgore told POLITICO in a statement: “Please understand that our corporate policy is not to discuss personnel matters (other than to confirm employment and dates of employment) with outside sources, including media. Thus, I must respectfully decline to comment on your questions or any allegations you may be looking into that concern current or former employees of the association.”

After POLITICO published its reporting Sunday evening, the Cain campaign said in a statement that the “political trade press are now casting aspersions on his character and spreading rumors that never stood up to the facts,” but the campaign did not deny the details of the report.

“Fearing the message of Herman Cain, who is shaking up the political landscape in Washington, Inside the Beltway media have begun to launch unsubstantiated personal attacks on Cain,” the campaign said in a statement. “Sadly, we’ve seen this movie played out before — a prominent Conservative targeted by liberals simply because they disagree with his politics.”

The revelations come at a time when Cain is riding high in the polls, with a candidacy that relies heavily on his claims that his experience as a businessman and the former head of Godfather’s Pizza has prepared him to be president.

But the Republican presidential hopeful also has begun to face increasing scrutiny in the news media over his management style as he presides over an unorthodox campaign that has seen the departures of several aides and struggled to take advantage of Cain’s sudden vault to the head of the pack.

Cain, who has been married to his wife Gloria for 43 years, did tell at least one campaign staffer this year about the possibility that claims of sexual harassment could surface, according to the aide. Cain, this person said, described a case in which he fired an employee in 1990s and the woman alleged sexual misconduct or harassment. Cain told the campaign staffer he had won the case and that the woman had paid his legal fees. The aide had no further details.

Cain was head of the restaurant trade group after he left as CEO of Godfather’s Pizza. He has often referred to his experience running the pizza company but speaks less often about his tenure atop the association. The year before he took the helm, the association represented about 150,000 food service establishments, had roughly 115 employees and a government affairs budget of nearly $20 million. But it was not known as a lobbying powerhouse.

Cain tried to change that, hiring more lobbyists and taking a much more public role in advocating for the industry than his predecessor had. Boasting of the shift in his book, Cain noted that during his tenure, the restaurant association made its first appearance on Fortune magazine’s list of Washington’s 25 most influential interest groups (it rose as high as 15th).

Information about the incidents was apparently closely held, even among association board members. But one woman’s complaint apparently did make its way to at least some figures on the governing board when, at an association event, one board member got word that a female employee had complained about Cain’s advances, according to a source who was at the event.

The source said the board member asked the woman directly about the episode and was told that Cain had invited her up to his suite at a prior association event.

Ron Magruder, Denise Marie Fugo and Joseph Fassler, the chairman, vice chairwoman and immediate past chairman of the National Restaurant Association board of directors at the time of Cain’s departure, said they hadn’t heard about any complaints regarding Cain making unwanted advances.

“I have never heard that. It would be news to me,” said Fugo, who runs a Cleveland, Ohio, catering company, adding such behavior would be totally out of character for the Cain she knew. “He’s very gracious.”

Fassler, who helped bring Cain on board as CEO of the restaurant association, said any inappropriate behavior was not brought to his attention and that he would be upset to learn it had gone on and he was not made aware of it.

“That’s a shock to me,” Fassler said. “As an officer during all of Herman’s years there as a paid executive … none of that stuff ever surfaced to me. Nobody ever called me, complained about this, nor did I ever hear that from Peter Kilgore, nor did I ever hear that from Herman Cain.”

Fassler — who ran a Phoenix food-service company and finished his term as chairman the month before Cain’s June 1999 departure but remained on the board’s executive committee — described Cain as treating men and women identically and asserted it was “not within his character” to make unwanted advances. “It’s not what I know of him,” Fassler said.

Much like Fassler, almost all board members remember Cain fondly and say he left on good terms.

Cain was “extremely professional” and “fair” to female staffers at the restaurant association, recalled Lee Ellen Hayes, who said she “worked fairly closely with” Cain in the late 1990s, when she was an executive at the National Restaurant Association Education Fund, a Chicago-based offshoot of the group.

Cain’s treatment of women was “the same as his treatment of men. Herman treated everyone great,” said Mary Ann Cricchio, who was elected to the board of the restaurant group in 1998. She said Cain left such a good impression on the organization that when he spoke at a group event in January of this year, as he was considering a presidential bid, “he had unanimous support in the room.”

Revelations about the settlements come as members of the association’s board planned to meet this month to talk about ways to use the organization’s clout to boost Cain’s campaign.

Ideas to be discussed included making a donation to Cain from the organization’s political action committee, which typically doesn’t contribute to presidential campaigns, and, more significantly, organizing a fundraiser for his campaign.
