The Dems and media were on him almost constantly, best I remember. It was also reported on the news that he felt that the media coverage of him was distracting from the things that needed to get done, and he felt that he needed to resign so that legislation could move forward.
Well, it’s almost identical to the reasons Sarah Palin resigned in that case, since she was being hounded with ethics charges and negative media attention that she said was a distraction. With the possible exception that she wanted to capitalize on her media fame in the entertainment/media industry before her 15 minutes were up.
