(Newser) – Potential trouble for Christine O'Donnell: The FBI is investigating whether she used campaign money for personal expenses, reports the AP. (The story is based on an anonymous source, and it notes that nothing has been referred to a grand jury.) O'Donnell raised $7.3 million in her unsuccessful run for the Senate in Delaware, and she has been hit with allegations of shady spending in the past by former campaign aides and by the watchdog group Citizens for Responsibility and Ethics in Washington. Salon reported on the latter in September.



A spokesman for O'Donnell's campaign tells ABC that the AP report is overblown: "The anonymous source seems politically-motivated and may well be tied to the ultra-liberal, George Soros-financed, former Sen. Biden staffer-run CREW complaint."
