The Department of Justice is investigating whether members of Rep. Michele BachmannMichele Marie BachmannBachmann won't run for Franken's Senate seat because she did not hear a 'call from God' Billboard from ‘God’ tells Michele Bachmann not to run for Senate Pawlenty opts out of Senate run in Minnesota MORE’s (R-Minn.) presidential campaign, including her husband, Marcus Bachmann, illegally coordinated with a super-PAC.

The New York Times reported on Friday that a former Bachmann campaign staffer filed complaints with the Federal Election Commission and the FBI alleging he overheard a conversation between the head of a super-PAC and a senior adviser to the Bachmann campaign coordinating TV and radio ad buys ahead of the 2012 Iowa caucuses.

Super-PACs are forbidden from coordinating election strategies with campaigns.

The report says Bachmann staff members have characterized the person who made the complaint as a “disgruntled employee who had limited responsibilities.”

Bachmann was briefly a serious contender for the Republican presidential nomination after she won the Ames, Iowa, straw poll in August 2011. Her campaign flamed out shortly after, and she withdrew after a poor showing in the Iowa caucuses.

That failed presidential bid has also sparked an ethics investigation into alleged improper payments to campaign consultants. Bachmann has said she will not seek reelection to Congress in 2014.

The DOJ does not confirm nor deny whether matters are under investigation. Bachmann’s office did not return a request for comment.
