Last april, I made a huge mistake. And I'm trying to make amens for that. I can detect alcohol on your breath. Reporter: Lemberg's drunk driving arrest has been publicized. It was her behavior before -- trying to keep you from tripping over. You don't need to be slapping his hands away. Reporter: And after her arrest that led to this civil case. An austin attorney has filed a petition to have her removed from office. You just ruined my career. Reporter: What may have been more detrimental to her career, is what happened next. County sheriff's deputies testified monday that the night of her arrest, she was rude, angry, loud and belligerent. This jail video shows her stomping, kicking, sticking her tongue out. Even gesturing with her fingers as if she was firing a gun. We asked you to stop kicking the door. And you didn't stop kicking the door. Reporter: At one point, she had to be strapped into a restraint chair, a spit guard placed over her head. Are you going to listen to me? I'm not going to listen to you. Reporter: She has issued a public apology and gone to rehab. But she refuses to resign. I cannot imagine that she could keep her job based on her behavior. Threatening the officers.
