Sources in the GOP say that the Republican National Committee is considering calling for the resignation of Idaho senator Larry Craig.
Craig entered a guilty plea to misdemeanor disorderly conduct following his arrest in a Minneapolis men's room.
Airport police recently released an audio tape of Craig and the arresting officer. On the tape the officer accuses Craig of lying, and Craig in turn accuses him of entrapment.
Meanwhile, more of Craig's Republican colleagues are distancing themselves from the lawmaker.
