Pure arrogance on her part. She and Sandy Burglar are typical of the Clinton crowd who believe that the rules do not apply to them. Put her in jail and throw away the key.
What I don't understand is why she was not arrested. I have to think that they have had the goods on her for awhile. Why let her just walk? Firing is not enough. I hope there's a good reason for their reluctance to get tough with McCarthy.
