The (Columbia, S.C.) State newspaper published e-mails last week between Sanford and Maria Belen Chapur when Sanford publicly confessed he had been unfaithful to his wife. The confession came after he returned to South Carolina from Argentina, ending a weeklong mystery as to his whereabouts.
Chapur issued a statement to Argentine TV station CN5 Sunday in which she insisted she would not speak about her private life "as it just belongs to me." She denied press accounts indicating that the source of the e-mail leak was another man she had been friendly with.
She said she thinks she knows who the leaker was, although she cannot publicly name him because she does not have sufficient proof, The New York Times reported.
Chapur said her Hotmail e-mail account was "hacked" in late November and the hacker sent the e-mail messages to The State as well as to the man she now says was not the source of the leak.
She prefaced her statement to CN5 by saying she wanted to "clarify certain incorrect things that are being spread worldwide" because she wants to put an end to a controversy that "is of great pain" to her and her two children, as well as her family and friends.
Sanford decided to serve out the remaining 18 months of his term after considering resigning, his spokesman told ABC News.
"Given everything that has gone on, it's obviously something he considered, but he's determined to serve out his term," Sanford's communication director Joel Sawyer, told ABC.
