FEC clarifying information about Sen. Baldwin's re-election campaign

WISCONSIN (CBS 58) -- Federal Election Commission officials are working to clarify information about Senator Tammy Baldwin’s re-election campaign.

The FEC says Baldwin's campaign may have accepted a donation too big under federal rules. 

Under federal law, individuals and unregistered PACs can donate up to $2,700 to a candidate. 

The paperwork does not say how much money was donated in this case.

The FEC says these checks are common and generally due to a simple systems data error.
