The New York Times reported Thursday it has reviewed the grand jury subpoena. The department is apparently investigating allegations of illegal coordination between Bachmann's campaign and the National Fiscal Conservative Political Action Committee, the Minneapolis Star Tribune reported.
Bachmann, who has announced she will not seek a new term next year, has represented Minnesota's sixth district in Congress since 2007. She announced she was a candidate for the GOP presidential nomination in June 2011 and suspended her campaign in January 2012 after she came in sixth in the Iowa caucuses.
Peter Waldron, a Florida minister who worked for the Bachmann campaign and went public with allegations of ethical misdoings, told the Star Tribune he warned Bachmann's husband Marcus of federal laws banning coordination between Super PACs and campaigns. He said Marcus Bachmann sent him an email describing a phone conversation with the head of the NFC PAC, who told him a donor had agreed to give $7,000 for a mailing.
