(CNN) -- Herman Cain's wife said she doesn't believe the sexual harassment allegations against her husband because "he totally respects women."
Gloria Cain made the remarks in an interview to air Monday on Fox's "On the Record with Greta Van Susteren."
"I know that's not the person he is. He totally respects women," Gloria Cain said.
Responding to the latest allegation that Cain groped a woman in a car, she added: "I looked at especially this last lady and the things that she said and I'm thinking he would have to have a split personality to do the things that she said."
Last week, during an appearance on ABC's "Jimmy Kimmel Live," Cain said he still has the support of his wife.
"My own wife said that I wouldn't do anything as silly as what that lady was talking about, because she does know me," Cain said about one of the accusers, Sharon Bialek. He added: "I've been married for 43 years to the same woman and I'm proud of it."
At least four women have accused the GOP presidential hopeful of sexual harassment.
In a statement last week, Cain campaign spokesman J.D. Gordon said, "There have been a number of interesting revelations that the public has learned about these women over the past few days. We hope the court of public opinion will take this into consideration as these women continue to try and keep this story alive."
The attorney for a woman who accused Cain of sexual harassment in the late 1990s said Thursday his client is not prepared to hold a news conference about the allegations until all the other reported victims agree to join her.
Joel Bennett said his client, Karen Kraushaar, has tried to reach two other women who also claim they were sexually harassed by Cain during his 1996-99 stint as head of the National Restaurant Association.
Another accuser, Bialek, has agreed to attend a joint news conference with Kraushaar, but without the participation of all the alleged victims, Kraushaar doesn't want to proceed, Bennett told reporters.
The sexual harassment accusations have dominated Cain's campaign since they were first reported October 30 by Politico. He had surged to the top of the polls with former Massachusetts Gov. Mitt Romney, but now faces questions about his moral fiber as well as his campaign's ability to deal with the controversy.
While controversy swirls around Cain, his campaign is continuing to see a major financial boost.
The campaign announced Thursday it has brought in more than $9 million since October 1.
Cain has repeatedly and vehemently denied the sexual abuse allegations. Some analysts have said the accusations are helping him to build support among conservative activists and the impressive fund-raising totals are one sign of that.
While Cain has soared in popularity in his bid for the Republican presidential nomination, his wife has remained out of the spotlight. Gloria Cain is rarely seen on the campaign trail and had been unavailable to media outlets clamoring to speak with her.
Cain, 65, has said previously he's trying to keep his family protected from the ups and down of running for president. Gloria Cain had a pacemaker implanted in 2005 to help with a serious heart fibrillation, according to his book "This is Herman Cain! My Journey to the White House."
In the interview to be broadcast Monday, Gloria Cain said she stops herself from thinking what life might be like if her husband becomes president.
"Sometimes I let myself go there. but then I try to pull myself back," she said. "I don't want to start projecting too far in the future because then I would worry more, so I try to take one day at a time and in that way."
She added: "If or when that happens, I have faith that the Lord will have me ready to do whatever I need to do that's going to help him."
