From an exclusive report by David Shuster at Huffington Post:
While Congresswoman Michele Bachmann was announcing her retirement to much fanfare in the media, according to information given exclusively to Take Action News, the FBI was busy collecting potentially damaging evidence against her from two former campaign aides.
According to sources close to the criminal investigation of Bachmann's presidential campaign, the FBI has now been given sworn testimony and documents alleging Bachmann approved secret payments to Iowa state Senator Kent Sorenson in exchange for his help and support in that state's 2012 Presidential caucuses. Ethics rules explicitly prohibit Iowa lawmakers from accepting payments from Presidential campaigns or PACs. Investigation sources tell Take Action News the FBI is examining money laundering allegations against Bachmann, as well as possible wire fraud and mail fraud.
As we detailed on my nationally syndicated radio and YouTube show Take Action News this past Saturday, the key claims against Bachmann are coming from two of her former campaign insiders -- former Congressional chief of staff Andy Parrish and former national field coordinator Pete Waldron. Waldron has filed a complaint with the Federal Elections Commission, alleging the payments to State Senator Sorenson were improper. Parrish has provided an affidavit to investigators, confirming Bachmann knew of and approved the payments.

Not much to add from me - it would appear self-evident that this is why Rep. Bachmann decided not to run for re-election in 2014. #GoodbyeGOP and #BuhbyeBachmann.
