A top adviser in Michele Bachmann's presidential bid has filed a complaint with the Federal Elections Commission alleging campaign finance violations involving the Republican congresswoman's failed presidential campaign and her independent political action committee, the Star Tribune reported.

The complaint was filed by Peter Waldron, an evangelist the Bachmann campaign brought on board to help the campaign reach more Christian conservatives.

Last week Waldron had alleged that the congresswoman's presidential campaign had not paid five staffers who refused to sign confidentiality agreements.

Waldron is getting in some other parting shots, including the claim he made to Buzzfeed that Bachmann's former debate coach, Brett O'Donnell, developed an "unnatural" and "Rasputin-like" relationship with her, and that O'Donnell prohibited the candidate from sleeping in the same room as her husband. O'Donnell sharply denies that: "Your source for your outrageous claim is a disgruntled campaign employee who has little knowledge of reality," O'Donnell said in an email to Buzzfeed. "Why is this news now anyway?"

Waldron has a colorful history, including an arrest on terrorism charges in Uganda in 2006, The Atlantic noted in a 2011 story.
