Documents recently released from the federal agency show the South Carolina Republican's campaign committee accepted 42 donations over the $2,000-per-person limit. The $68,106 in excessive donations were made in 2003 and 2004, when he won his Senate seat.
The agency said all but $5,000 was reallocated to a different part of the campaign, which involved a primary race, a runoff and the general election.
DeMint spokesman Wesley Denton noted only $5,000 had to be refunded out of more than $10 million raised. He says the campaign is happy to move forward after the exhaustive 3-year audit.
