O'Donnell's lawyer alleged in a letter to the U.S. Attorney's office that Melanie Sloan, executive director of Citizens for Ethics and Responsibility in Washington, knowingly made false statements in the complaint against O'Donnell. O'Donnell's lawyer says the complaint was based on an affidavit from a former campaign worker that contained false information and was not properly vetted.
Sloan, a former prosecutor, said O'Donnell and her lawyers were unfamiliar with the law and that CREW was unconcerned.
Federal prosecutors informed O'Donnell's campaign lawyer Friday that they were closing their review and did not intend to pursue criminal charges.
