Secretary of State Hillary Rodham Clinton is still appealing to supporters to help her retire her presidential campaign's debt.

"Hillary's campaign still has a few vestiges of debt that I know she would like to see paid in full," the ex-president wrote. "Will you reach out today to help Hillary this one last time?"

The appeal says that donors could be selected to spend the day with Bill in New York City.

It's not unusual for presidential candidates to take years to pay down debts for expensive campaign operations. 

But when Hillary dropped out of the race in June 2008, she had what was believed to be the largest campaign debt in history. A report at the time said she had about $9.5 million in unpaid bills to vendors as well as the $11.4 million she lent her campaign.

Through December 2008, Clinton had over $5.9 million in debt, but her campaign's most recent filing with the Federal Election Commission shows that she now has $771,000 in unpaid debts.
