John Edwards on the campaign trail in 2008.

Two-time presidential candidate John Edwards was indicted today over massive sums of money spent to keep his mistress in hiding during the peak of his 2008 campaign for the White House. Campaign donors provided the funds. Prosecutors in North Carolina say that violates federal election laws, while Edwards lawyers maintain that the money was kept separate from campaign expenses and his only wrongdoing was hiding an affair from his wife.
