In an interview with the conservative blog RedState on Wednesday, Perry said he and his campaign learned about the allegations in a Politico story published Sunday.
Perry says his campaign “had absolutely nothing to do with it.”
That story said at least two National Restaurant Association employees had filed complaints against Cain, who led the trade association in the 1990s. A third employee since has told The Associated Press that Cain expressed unwanted behavior toward her, but she did not file a formal complaint.
Cain’s campaign on Wednesday blamed Perry for encouraging the story and demanded an apology. Perry’s campaign has repeatedly denied having a role.
