This is a surprise:
Fox News reports:
Bachmann claims her decision was not influenced by concerns that she would not be re-elected, or by recent inquiries into her 2012 presidential campaign.
In January, a former Bachmann aide filed a complaint with the Federal Election Commission, claiming Bachmann made improper payments to an Iowa state senator who was the state chairman of her 2012 presidential run. The aide, Peter Waldron, also accused Bachmann of other FEC violations.
Bachmann says she considered not running again for her House seat in 2012 after her failed presidential bid, but felt another Republican candidate would not have enough time to adequately prepare for the race.
“I will continue to work overtime for the next 18 months in Congress defending the same constitutional conservative values we have worked so hard on together,” Bachmann says in the video.
Bachmann had given few clues she was considering leaving Congress.
