The Arkansas Republican Party ultimately reimbursed the state for the $19,029.25 payment via a check dated Sept. 14 -- only after Campbell called attention to it.

According to the public records Campbell released, the lectern invoice was also altered after the fact by Sanders' executive assistant, to add the “To Be Reimbursed” notation.

Henning, Sanders spokesperson, has said the use of a state credit card for the lectern was "an accounting error."
