WASHINGTON (AP) — A third former employee considered filing a workplace complaint against Herman Cain over what she considered aggressive and unwanted behavior when she and Cain, now a Republican presidential candidate, worked together during the late 1990s, the woman told The Associated Press on Wednesday. She said the behavior including a private invitation to his corporate apartment.

The woman said he made sexually suggestive remarks or gestures about the same time that two co-workers had settled separate harassment complaints against Cain, who was then the head of the National Restaurant Association.

She did not file a formal complaint because she began having fewer interactions with Cain, she said. Afterward, she learned that a co-worker — one of the two women whose accusations have rocked Cain’s campaign this week — had already done so. She said she would have had to file if they hadn’t.

The woman spoke only on condition of anonymity, saying she feared retaliation. She was located and approached by the AP as part of its investigation into harassment complaints against Cain that were disclosed in recent days and have thrown his presidential campaign into turmoil. She said she was reluctant to describe the encounters she had with Cain when they worked together at the Washington-based restaurant trade group.

The employee described in conversations with the AP over several days situations in which she said Cain told her that he had confided to colleagues how attractive she was and invited her to his corporate apartment outside work.

His actions “were inappropriate, and it made me feel uncomfortable,” she said.

Cain’s campaign manager, Mark Block, replied, “No comment,” when he was asked Wednesday about the new allegations.

The AP confirmed that the employee worked at the restaurant association with Cain during the period in question, that she has no party affiliation in her voter registration in the past decade and is not identified as a donor in federal campaigns or local political campaigns. Records show she was registered as a Democrat at one point previously.

Though trying to project an image of campaign business as usual, Cain appeared frazzled at times Wednesday and couldn’t escape the questions that have dogged him since a published report Sunday night that at least two women had complained about his behavior while at the restaurant association and had been given financial settlements. The controversy has arisen two months before the leadoff Iowa caucuses and as polls show Cain at the head of the GOP field alongside former Massachusetts Gov. Mitt Romney.

As the day began, Cain said, “There are factions that are trying to destroy me personally, as well as this campaign.” He didn’t say to whom he was referring, but he said “the voice of the people” is stronger.

Cain was supposed to take questions after a speech to health care professionals, but he ultimately refused and left the hotel through a back door.

“I’m here to visit with these doctors, and that’s what I’m going to talk about, so don’t even bother asking me all of these other questions that you all are curious about, OK? Don’t even bother,” a testy Cain told a throng of reporters.

When pressed about the week’s previous allegations, Cain raised his voice and said “What did I say? Excuse me. Excuse me!” as hotel security led him through a hallway jammed with journalists in a Washington suburb. “What part of ‘no’ don’t people understand?”

Meanwhile, another of Cain’s accusers appeared increasingly reluctant to speak publicly, though her lawyer took the first steps for her to do so. Attorney Joel P. Bennett contacted the association on Wednesday and asked it to release his client from the confidentiality arrangement she had agreed to so that she could talk openly about her allegations and respond to Cain’s assertion that her complaints were “totally baseless and totally false.”

Cain has declined to say whether he will ask his former employer to terminate confidentiality restrictions on the two women who accused him of sexual harassment in the 1990s while he was head of the trade group. Block said the campaign would address that question “when it’s appropriate.”

Sue Hensley, a restaurant association spokeswoman, confirmed that Bennett contacted the trade group and was told to contact its outside counsel. Hensley said Bennett expected to meet with his client and make the request on Thursday.

Confidentiality agreements that commit both sides to silence are common in financial settlements of an employee’s sexual harassment claims, lawyers for management and employees said. Violating such an agreement can lead to a complaint in court and an order to pay damages, or at least the other side’s attorney’s fees, said Sarah Pierce Wimberly, a partner in the Atlanta office of the Ford and Harrison law firm.

But when the silence is broken, it’s often hard to find the source of the leak, said Robert Kelner, a partner in the Covington and Burling firm’s Washington office. He said, “The truth is, when parties enter into these confidentiality agreements around a settlement, they usually understand that there is less than 100 percent certainty that the information is truly going to remain confidential.”

It’s not clear if Cain himself was part of the settlement or whether it just involved the association and the woman. But he almost certainly would be bound by it, as the association’s former president.

Over the past two days, Cain has acknowledged he knew of one agreement between the restaurant association and a woman who accused him of sexual harassment. He has said the woman initially asked for a large financial settlement but ultimately received two to three months’ pay as part of a separation agreement. Cain also acknowledged remembering one of the woman’s accusations against him, saying he stepped close to her to make a reference to her height and told her she was the same height as his wife.

He has said he is not aware of agreements or settlements with any other women, though Politico — which first disclosed the allegations — reported that the trade group had given settlements to at least two female employees who accused him of inappropriate sexual behavior.

In media interviews since the story broke Sunday, Cain has offered conflicting accounts of what happened during his tenure at the trade group in Washington. He later acknowledged knowing about one settlement but said he did not know how much was paid. The New York Times reported Tuesday that one payout was $35,000, equivalent to one year’s salary for one of the women.

The pressure on Cain only increased when a pillar of the GOP establishment suggested that the Georgia businessman should ask the association to waive the confidentiality agreements so that the woman can talk openly about her allegations.

“What are the facts?” asked Mississippi Gov. Haley Barbour on MSNBC. “If you have a confidentiality agreement that keeps the public from finding out something that the public is interested in knowing the facts, you ought to go on and get the facts out.”

“Herman Cain’s interest is getting this behind him,” added Barbour, a former Republican National Committee chairman.

A former talk show host, Cain is a self-styled political outsider who has attracted tea party support and, up until now, has weathered a series of stumbles that have many GOP luminaries questioning his ability to run a viable campaign much less win the party’s nomination. Conversely, Romney is running his second national campaign and has spent the past few weeks shoring up support among the GOP establishment for a nomination fight many Republican insiders think is his to lose.
