WASHINGTON - Two women employees complained of sexually suggestive behavior by Herman Cain when he headed the National Restaurant Association in the 1990s, Politico said on Sunday.
The women ultimately left the trade group after signing agreements that gave them financial payouts to leave the association and barred them from talking about their departures, the report said.
Cain's campaign called the allegations "unsubstantiated personal attacks."
The report could damage Cain's surprisingly strong bid to win the Republican nomination to challenge US President Barack Obama in 2012. Cain, the former CEO of Godfather's Pizza, has taken a lead in many opinion polls of Republicans in recent weeks despite never having held public office.
Politico said at least two female employees, whom they have identified but decided not to name, complained to colleagues and senior association officials that inappropriate behavior by Cain made them angry and uncomfortable.
