ABC News’ John Berman and Susan Archer report:

Herman Cain’s wife Gloria, speaking publicly for the first time, says in a TV interview that she doesn’t believe allegations of sexual harassment against her husband.

In an interview set to run Monday night, Gloria Cain tells Fox News’ Greta Van Susteren that she can’t see her husband doing the things that have been described by his accusers.

“You hear the graphic allegations and we know that would have been something that’s totally disrespectful of her as a woman,” Gloria Cain said. “And I know the type of person he is. He totally respects women.”

After listening to the barrage of accusations about her husband, Gloria Cain said, “I’m thinking he would have to have a split personality to do the things that were said.”

Herman Cain says that his wife was already aware of the allegations made back in 1999, when he was head of the National Restaurant Association.

Gloria Cain has stayed out of the spotlight since her husband started running for the Republican nomination. But with the GOP frontrunner in the midst of sexual harassment allegations and Cain’s supporters wanting to meet their possible future first lady, Gloria Cain is finally breaking her silence.

Herman Cain has said that his wife is a very private person, and unlike other political wives would not be partaking in the rigors of the campaign trail. He has campaigned alone while Gloria has stayed at home. She also suffers from a serious heart condition and had a pace-maker implanted several years ago.

Gloria Etchison met Herman Cain when he was a student at Morehouse College and she was a student at Morris Brown College. He writes about their 43-year marriage in his book “This Is Herman Cain!: My Journey to the White House.” In it he describes that when he decided to run for president, she was nervous about the increased scrutiny that comes with being a presidential candidate, and what it would mean for the family.

“Being terrified came from the perception that you are constantly under the microscope,” Herman Cain told ABC News’ Jon Karl this month.
