There's more bad news for Idaho Republican Sen. Larry Craig.

Listen: Senator's Arrest Interview

A recording of his arrest at the Minneapolis-St. Paul airport on charges of lewd behavior in a bathroom has been made public.

CNN aired portions of the tape on Thursday.

"I need to make this quiet," Craig is heard saying, before the officer reads him his Miranda rights. Craig tells the officer he understands his rights, and then the two engage in a sometimes heated discussion about events leading up to the arrest.

"I don't seek activity in bathrooms," he says at one point on the tape.

The officer who arrested Craig in a police undercover operation at an airport men's room accused the senator of lying to him during the interrogation.

On the tape, the Idaho Republican senator, in turn, accuses the officer of soliciting him for sex.

"I'm not gay. I don't do these kinds of things," Craig told Sgt. Dave Karsnia minutes after the two men met in a men's room at the airport on June 11.

"You shouldn't be out to entrap people," Craig told the officer. "I don't want you to take me to jail."

Karsnia replied that Craig wouldn't be going to jail as long as he cooperates.

At one point during the interrogation, the officer told Craig: "You're not being truthful with me. I'm kind of dissapointed in you, senator."

Police: Pattern Followed

Craig's alleged conduct closely followed the pattern described in several of the arrests. In his report, Sgt. Dave Karsnia said he went into a stall shortly after noon on June 11 and closed the door. Minutes later, the officer said he saw Craig peering into his stall through the crack between the door and the frame.

After a man in the adjacent stall left, Craig entered it and put his luggage against the front of the stall door, "which Sgt. Karsnia's experience has indicated is used to attempt to conceal sexual conduct by blocking the view from the front of the stall," said the complaint.

The complaint said Craig then tapped his right foot several times and moved it closer to Karsnia's stall and then moved it to where it touched Karsnia's foot. Karsnia recognized that "as a signal often used by persons communicating a desire to engage in sexual conduct," the complaint said.

Craig then passed his hand under the stall divider into Karsnia's stall with his palm up and guided it along the divider toward the front of the stall three times, the complaint said.

The 40 others caught up in the sting, according to the police reports, included airport and airline employees, an account executive with Revlon, an IT consultant for Ernst & Young, a 3M executive and a Lands End employee.

Support Waning

News of the tape comes the same day that a member of the Senate Republican leadership suggested Craig resign in the wake of his guilty plea to the charges.

Nevada Sen. John Ensign, who chairs the party's senatorial campaign committee, told The Associated Press that it's a different situation between pleading guilty and "just being accused of something."

Ensign stopped short of calling on Craig to resign his seat, but said that's what he would do if he were in Craig's position. He said that Craig will have to make that decision on his own, but said he thinks the pressure "will continue to build."

Craig has agreed to step down from his committee posts.

"Sen. Larry Craig has agreed to comply with Leadership’s request that he temporarily step down as the top Republican on the Veteran Affairs Committee, Appropriations Subcommittee on the Interior, and Energy and Natural Resources Subcommittee on Public Lands and Forests. This is not a decision we take lightly but we believe this is in the best interest of the Senate until this situation is resolved by the Ethics Committee," said a statement by Republican Leader Mitch McConnell, Republican Whip Trent Lott, Conference Chairman Jon Kyl, Policy Committee Chair Kay Bailey Hutchison, and Senatorial Committee Chair John Ensign.

Sen. John McCain, R-Ariz., and Sen. Norm Coleman, R-Minn., the state where Craig was arrested, became the first senators to join Rep. Peter Hoekstra, R-Mich., urging Craig's resignation.

McCain, a candidate for the presidency, told CNN the decision was Craig's to make, "but my opinion is that when you plead guilty to a crime, you shouldn't serve. That's not a moral stand. That's not a holier-than-thou. It's just a factual situation."

Former Massachusetts Gov. Mitt Romney, another GOP presidential hopeful, in whose campaign Craig was playing a prominent role until he quit amid the scandal, told CNBC, "He's disappointed the American people." But he stopped short of calling for Craig's resignation.

Craig's "I'm not gay" declaration is not sitting well with some gay activists, either, some of whom view Craig, a family-values conservative, as a classic hypocrite tragically imprisoned by the "homophobia" he helped to create.

Matt Foreman, executive director of the National Gay and Lesbian Task Force, said Craig contributed to his own problems by living in denial. Foreman said most people living in the closet, particularly those in power, dig themselves in so deeply "they can't see a way out."

William Leap, an anthropology professor at American University, said his research indicates that up to half of those who engage in male bathroom sex would consider themselves heterosexual.
