COLUMBIA, S.C. (AP) — South Carolina's governor appears to have closed the door on appointing Stephen Colbert to the U.S. Senate, all because he didn't know the state drink was milk.

During "The Colbert Report" on Thursday, Colbert urged fans to send Gov. Nikki Haley messages on Twitter telling her why he would make a great senator from his home state. Haley is appointing a senator after Jim DeMint announced he is resigning at the end of the year.

Thousands of messages poured into the governor's official account with the hashtag "SenatorColbert."

Haley responded Friday on her Facebook page with a link to her April appearance on Colbert's show, where the host, who was raised in Charleston, did not know the state beverage is milk.

Haley wrote that was a "big mistake."
