The Federal Election Commission has imposed a $375,000 fine on President Barack Obama’s 2008 presidential campaign for reporting violations, Politico is reporting, citing as-yet-unpublished FEC documents.

The fine appears to stem from missing reports for close to 1,300 donations totaling more than $1.8 million, according to Politico, which obtained a copy of a conciliation agreement that was shared with the Republican National Committee, one of the original complainants. The fine is described as one of the largest-ever imposed on a presidential campaign.

Obama campaign spokeswoman Katie Hogan told Politico that at the time, the Obama team was collecting record contributions from more than 3 million donors, and that “the very few outstanding questions about the $750 million that was raised have now all been resolved.”

In other FEC news, Commissioner Cynthia Bauerly has announced that she will resign effective Feb. 1. The move is sure to increase pressure on Obama to name new members to the frequently-deadlocked FEC, which is comprised mostly of holdover commissioners.

Bauerly, a Democrat, is one of five commissioners on the six-member commission whose terms have expired. Activists opposed to unrestricted political money have become increasingly shrill in their demands that Obama name new commissioners, staging press conferences and launching a petition drive aimed at forcing a White House response.
