New York- Television producer Andrea Mackris speaks to the Daily News yesterday about her sexual harassment lawsuit against Fox News’ Bill O’Reilly. Bill O’Reilly’s accuser blasted him for pursuing a campaign of sleaze against her – and warned that her 74-year-old dad is out for blood.

Andrea Mackris told the Daily News yesterday that the Fox talk-show host had “a lot to answer for, to his wife and to his God.”

In her first extensive newspaper interview, Mackris talked about how hard the last two weeks have been on her and her dad.

“Like any father, he can’t stand the idea that this happened to his daughter,” Mackris said with her lawyer, Benedict Morelli, at her side. “If he had his way, he’d challenge Bill O’Reilly to a duel.”

Her dad, Constantine, who lives in St. Louis, and the rest of her family has known about the sex-harassment accusations from the start, she said. “I can only imagine what my mom thinks.”

Her mother Marilyn, 65, has multiple sclerosis and walks with two canes.

Mackris, 33, said, “What’s been going on, no human being could have anticipated.

“Bill O’Reilly promised me that he would destroy any woman who accused him of anything like this, and he’s proving that. They’ve been telling reporters stories about me having crushes on people, including O’Reilly. That I get drunk in restaurants, that I have fights in hotels, that I wrote a book to bring down Fox and O’Reilly. It’s all garbage.

“We tried to negotiate this in private and they’ve blown that. There have been no negotiations since the night before they filed their lawsuit.”

Mackris, an associate producer with “The O’Reilly Factor,” said her boss started making improper comments in 2002; they escalated after she returned to Fox following a stint at CNN this year, she said.

In three phone calls since August, he described his fantasies involving her, talked of his sexual escapades and even told her to buy a vibrator, she said.

O’Reilly filed a lawsuit hours before Mackris’ suit, claiming that she and Morelli demanded $60 million to buy her silence.

O’Reilly’s camp pointed out in their lawsuit that Mackris made no complaints to Fox News about the alleged harassment, and suggested that she simply could have hung up on O’Reilly, had she wanted.

“This is not just my boss, this is an incredibly powerful man,” Mackris explained. “When he asks me to jump, I say ‘How high?’ He’d already said that if anybody threatened him in this way, he would drag them through the mud.

“When he calls me and makes these comments, I’m supposed to say, ‘Mr. O’Reilly, that’s immoral’? I’m supposed to complain to human resources about this man, and then walk into work the next day to certain retaliation? What is happening to me now would have happened then, except I wouldn’t have had a lawyer by my side.”

O’Reilly’s lawyers have asked a judge to force Mackris to turn over any evidence, such as tape recordings, of O’Reilly’s alleged inappropriate comments.

“Why should we tell what evidence we have?” Morelli said. “They’ve forced our hand enough. Now they’re going on my timetable, and we want this trial to be in court.”

O’Reilly, a married father of two from Plandome, L.I., told The News he has been told not to talk about the case.

“I feel badly for his family,” Mackris said. “But I do not feel guilty. How is it my fault, what has happened here? I could have stood naked in front of him and there was still no way he should be allowed to get away with what he did.

“I put my faith, my ambition, my trust into the people at [Fox] and these people are now trying to destroy me.”
