WASHINGTON — Herman Cain says he will hold a news conference Tuesday afternoon in Phoenix to respond to the latest charges of sexual harassment brought by a Chicago woman who graphically described an incident she said took place in 1997.

With her attorney Gloria Allred at her side, Sharon Bialek offered specific details of the alleged advance she says Cain made when she was talking to him about getting a job. She is the fourth woman who has alleged that Cain engaged in inappropriate sexual behavior.

Cain has steadfastly denied the allegations.

The Cain campaign characterizes Allred as a high-profile Democratic Party donor and activist. In a statement announcing the news conference, Cain spokesman J.D. Gordon is questioning who’s paying Allred’s legal fees.
