His office says Mr. Sanford will be in Greer, near Spartanburg, today to talk about the federal law that requires states to issue drivers' licenses that meet new security mandates.
Last year, he locked horns with federal officials over the Real ID law, saying the changes were too costly. The Department of Homeland Security eventually granted the state an extension to comply with the law.
Mr. Sanford has been staying out of the spotlight since last month, when he revealed a yearlong extramarital affair with the Argentine woman.
He described the woman as his "soul mate" in a series of Associated Press interviews but said he would work to repair his relationship with his wife.
