The lawyer for federal worker Karen Kraushaar, who accused Republican presidential hopeful Herman Cain of misconduct, said Cain's behavior was harassment.
Kraushaar also said Cain, whom she accused of acting inappropriately toward her while he led the National Restaurant Association in the 1990s, could be called a "monster," ABC News reported Tuesday.
Kraushaar, whose identity was revealed Tuesday, said she had tried to avoid the media spotlight because she feared retaliation from Cain backers.
Joel Bennett, Kraushaar's attorney, last week said his client reported a "series" of incidents involving Cain when she worked in the trade group's communications department while Cain was chief executive officer in the late 1990s. She now is a spokesperson for the IRS Inspector General.
Kraushaar left the NRA after receiving a reported $45,000 settlement.
Cain has strongly denied any wrongdoing with Kraushaar or any of the other three women who have accused him of acting inappropriately. He previously blamed fellow GOP contender Rick Perry, the governor of Texas, the "liberal" media for fueling the scandal, and Tuesday blamed the "Democratic machine" for the emergence of one of his accusers.
Bennett said Cain's behavior "qualified as sexual harassment in our opinion," while not speaking about whether the alleged harassment was physical or verbal.
Since her identity was revealed, Kraushaar said she wanted to appear at a joint news conference with the other accusers.
Cain said Tuesday in a news conference he "will not be deterred by false, anonymous, incorrect accusations."
The latest allegations and plans came ahead of a nationally televised debate Wednesday among the eight Republican GOP contenders at Oakland University in Rochester, Mich. Jobs and the economy are supposed to be the focus.
GOP rival former Massachusetts Gov. Mitt Romney Tuesday called the allegations against Cain "particularly disturbing" and said, "They're going to have to be addressed seriously."
Kraushaar emerged from anonymity a day after Sharon Bialek went public with allegations against Cain, accusing him of groping her in a car in the late 1990s.
At Tuesday's news conference, Cain said he did not recognize Bialek and did not remember having any interaction with her.
"I have never acted inappropriately with anyone. Period," Cain said, adding, "I don't even know who this woman is."
Cain's campaign sent an e-mail to reporters attacking Bialek's credibility, detailing her involvement in lawsuits, bankruptcies and a paternity case. Bialek told CNN she had sought bankruptcy protection because of financial problems she experienced after her mother's death and during a custody battle over her son.
"Like millions of other people out there, you know, I'm struggling," she said.
As for Cain's criticism of her, Bialek told several TV interviewers she was not surprised.
"It's not about me," Bialek told NBC's "Today" show. "I'm not the one running for president."
