Former U.S. Senate candidate Christine O'Donnell says the Federal Election Commission has dismissed a complaint filed against her during last year's campaign by the Delaware Republican Party.

The state GOP accused O'Donnell and the Tea Party Express of violating FEC rules that restrict coordination between candidates and outside political organizations.

The complaint alleged that the Tea Party Express solicited donors to contribute to O'Donnell and that O'Donnell and the group worked jointly on advertising, breaching federal rules.

In a post on her Twitter account Thursday, O'Donnell says the FEC had dismissed the complaint, which she described as frivolous and politically motivated. O'Donnell's campaign lawyer also says the complaint has been dismissed, though an FEC spokeswoman says she can't confirm it.
