Investigation ends when Bachmann leaves

Rep. Michele Bachmann has decided not to seek re-election in 2014. An ethics investigation into how her campaign funds were used will end when she exits Congress at the end of her term.

The Republican Congresswoman announced the news in a video on her website on Wednesday. Bachmann said she didn't base the decision on the congressional ethics inquiry, and it's not because she's worried about her chances of getting re-elected. CNN's Dana Bash reports.
