Former employees tell ABC News that Cain was a regular on Washington's after-work bar scene, often with young women who worked with him at the National Restaurant Association, where he was president and CEO from 1996 to 1999.
Though some defenders say it was just Cain being personable and gregarious, Thursday the presidential candidate was pressed about new accounts that he asked one young female employee to return to his corporate apartment with him.
Cain told Fox News host Sean Hannity, "That is absolute fabrication, man," and said he had an apartment "near the airport because I traveled so much." Cain's wife Gloria had continued to live in Omaha after he took the job at the NRA, according to reports, and he often flew home to see her.
Cain told Hannity he never even made flattering remarks to an accuser he had allegedly asked to accompany him to his apartment.
"I didn't make those kind of compliments," said Cain. "I didn't say that she was hot, or that sort of thing. ... I know I didn't do that kind of stuff."
As ABC News has reported, two of the women who received settlements from the Restaurant Association are well known in government circles.
One, now in her forties, is single and registered as a lobbyist in New Jersey.
The woman who declined to speak publicly Friday is in her fifties now, married, and a spokesperson for a federal agency in Washington.
On Friday, she released a statement through lawyer Joel Bennett saying she was a victim of "a series of inappropriate behaviors and unwanted advances" while working for Cain at the National Restaurant Association.
"Mr. Cain knows the specifics" of the harassment complaint, Bennett said during a press conference in front of his Georgetown law office. "It had very specific incidents in it. If he chooses not to remember or to not acknowledge those, that's his issue."
Bennett read the woman's statement Friday afternoon after the restaurant industry association once led by the Republican presidential contender announced it would waive a confidentiality agreement that had barred her from discussing the harassment complaint she filed in July of 1999. Friday's disclosure provided few details about the specific incidents that led her to complain. However it did, for the first time, reveal that Cain allegedly made repeated, unwanted advances, and that there were alleged to have been multiple incidents over the course of "at least a month or two."
"She has decided not to relive the specifics of the incidents so I cannot give any further details," Bennett said.
Bennett said he did not want to characterize "what was physical and what was verbal," but that Cain's behavior "quailed as sexual harassment in our opinion."
