You're about to hear a secret tape of the senate's top republican. It involves his campaign discussing a plan to target a possible opponent, who happens to be hollywood star ashley judd. She says their talk reveals politics at its worst. He calls the tape a dirty trick. Here's abc's jim avila with the recording and the controversy it sparked. Reporter: If ashley judd thought the hollywood movie business was cutthroat, welcome to politics, where the most powerful republican in the senate, minority leader mitch McCONNELL CAN BERD PLOTTING To crush the actress's potential campaign against him during a period of the campaign. When anybody sticks their head up, do them out. Reporter: Mother jones magazine today publishing a tape recording of the private session, revealing possible campaign plans to attack judd's admissions of a personal struggle with depression. She is emotionally unbalanced. She's suffered some suicidal tendencies. Reporter: And her religious beliefs. In judd's autobiography, which McCONNELL'S AIDES APPARENTLY Read carefully, the movie star said, like st. Francis, she believes in a god who is close to nature and she talks to animals. She's an out of touch, hollywood liberal. Reporter: Is it fair game for you to question someone's mental health or religious sensibilities in a strategy session like that? Apparently they were bugging our headquarters, a nixonian move. This is what you get from the political left in america these days. Reporter: Judd, in a statement, called the tape an example of "the politics of personal destruction." Asked about the content of the MEETING, McCONNELL REFUSED. Reporter: That's not what i asked you. Only to repeat the same line, claiming to have been bugged, three times. The fbi says, at the senator's request, it is investigating the wire tapping allegations. Mother jones says it didn't make the tape and won't say who gave it to them, but denies the magazine broke any laws. To characterize it as a watergate-style bugging is inaccurate. Reporter: To characterize it as "how sausage is made" may be more accurate. Jim avila, abc news, washington.
