Washington ? Election watchdogs have directed Joe Biden’s 2008 presidential campaign to pay the U.S Treasury more than $219,000 to resolve issues caused by sloppy bookkeeping and accepting excessive contributions, including a discounted flight on a private jet.

The audit was released Friday by the Federal Election Commission. It determined that the Biden campaign accepted an improper corporate contribution in the form of a round-trip flight between New Hampshire and Iowa in June 2007 for three people. The Biden campaign paid GEH Air Transportation $7,911 for the first-class airfare, but regulators say the campaign should have paid the charter rate of $34,800.

The FEC also found that the Biden campaign could not document repaying at least $106,000 in donations that were over the limit, and the campaign was ordered to pay the U.S. Treasury more than $85,000 for stale-dated checks.

The Biden campaign also failed to disclose more than $3.7 million in payments and roughly $870,000 in debts.
