The U.S. Department of Justice is reviewing an email written by Rep. Michele Bachmann's husband in which he allegedly attempted to raise campaign funds and coordinate strategy through an outside "super PAC," reports the Star Tribune.
The Star Tribune says the email was obtained by the DOJ when it subpoenaed records from the National Fiscal Conservative Action Committee as part of a federal grand jury investigation into illegal campaign activities by the Bachmann camp.
MinnPost reports that campaigns are barred from coordinating ad strategy with super PACs, and according to a campaign finance experts, campaign staff cannot solicit donations for super PACs worth more than $5,000.
The Star Tribune reports the grand jury subpoena, first reported in the New York Times, represents a "major escalation" in the multiple federal and state inquiries that rose from alleged election law violations.
The allegations were first brought forward in January by campaign whistleblower Peter Waldron.
Officials representing Bachmann and the NFC PAC did not respond to requests for comment Friday, the Strib reports.
Bachmann announced in May that she would not seek a fifth term in Congress, stressing that her decision had nothing to do with lingering investigations of her presidential campaign.
