The Federal Election Commission has fined U.S. Rep. Michele Bachmann's 2010 campaign committee $8,000 for failing to properly report contributions and spending.

According to a FEC document dated May 2 and filed this week, Bachmann's campaign acknowledged that treasurer Daniel Puhl did not report $208,502 in donations and $206,499 in spending during the 2010 election cycle.

Between September 2010 and May 2011, Puhl amended five campaign finance reports to reflect the changes, as part of a "proactive internal review," documents show.

The violations came during Bachmann's record-setting 2010 campaign, when she raked in more than $13 million in contributions; at the time, it was the most raised by any U.S. House candidate in history.

The Minnesota Republican rode the windfall to a 13 percentage point victory over her opponent, DFLer Tarryl Clark, outraising her by $8.84 million along the way.

Bachmann, who has become a polarizing national figure during her time in Congress, announced Wednesday that she will not seek re-election to her U.S. House seat in 2014. The FEC will require an outsider auditor to review all her 2013 and 2014 campaign finance reports.

And as Bachmann prepares to serve the remainder of her term, she still faces several investigations -- including inquiries from the FBI -- into alleged campaign finance violations tied to her failed 2012 presidential run.
