A state audit says Lt. Gov. Mark Darr received more than $12,000 in improper expenses.
Darr said in the document released Thursday that he intends to make full restitution to the state.
The audit report, which was presented to a legislative committee on Thursday, says the first-term Republican should pay back $9,836 for excess travel reimbursements and $2,339 for improper use of his state credit card.
The document says Darr reimbursed $1,202 to the state to cover part of the credit card spending, with $1,137 due.
A spokeswoman for Darr said the lieutenant governor wouldn't comment beyond his response in the audit.
Darr was running for the GOP nomination for the 4th District congressional seat being vacated by Republican U.S. Rep. Tom Cotton but he dropped out in September.
