Sanford confirmed the engagement to CNN in a statement. The news was first reported by an Argentine publication. Sanford and his former wife divorced in 2010.
"Yes, we are engaged, and I’m both happy and excited for what that means,” Sanford said in the statement to CNN. “I have long expressed my feelings for her; she’s a wonderful person. My closest friends have met and love her, and I look forward to introducing her to still many more that have yet to do so."
Sanford refused to resign his governor's post when the affair was revealed, but did give up his post as head of the Republican Governors Association. He finished his term in 2010, did not seek reelection and was replaced by current Gov. Nikki Haley (R).
