The Federal Election Commission hit a prominent anti-abortion-rights group on Wednesday for sloppy record-keeping and failing to disclose hundreds of thousands of dollars in independent expenditures ahead of the last presidential election.

In a new report, the FEC wrote that an audit of the National Right to Life’s political action committee “revealed material misstatements” of numerous financial transactions, resulting in an $86,570 ending balance on the last day of the 2003-04 cycle.

FEC auditors also found that the PAC failed to disclosure more than half of the $3.72 million it spent on independent expenditures — television ads, direct mail and robocalls — during the 2004 election cycle.

National Right to Life’s PAC also did not disclose the occupations for more than 550 of it donors, the agency’s audit staff concluded. The full commission, which could choose to fine the PAC for the infractions, did not allege any wrongdoing in the report.
