The story about the fund is BS, if you read the whole original story, the ending sentence says no laws were broken. Same as the letter stuff, you know how congress works, just because a letter is sent out by staff does not mean that the congress critter even knew about it.
It's pretty funny - that Bachmann supporters point to House ethics standards (or lack thereof) as proof Bachmann did nothing wrong.
So tell me - do you approve of using tax monies for political events? Do you think Bachmann knew she was playing games with those monies by saying the event was a press conference when it was nothing of the sort?
