South Carolina Gov. Nikki Haley repaid about $10,000 for using the state planes to attend news conferences and bill signings.

The taxpayer-funded planes can only be used for free for official business.
The governor's office said it didn't realize that last year, lawmakers decided new conferences and bill signings were not considered official business.
