Where did you read that, because to be fired you need to do something wrong. The MSM still portrays this guy as a victim.
I don't know, it was in a post near the end of the day, yesterday. Actually, they didn't say that he was fired, they just said that he was no longer working for the campaign. It could have been any reason, not the least of which would be that he would be a big distraction, and too busy defending himself to be of any help.
