Nevada Sen. John Ensign says he is preparing to run for a third term, despite an ongoing federal investigation into an extramarital affair with the wife of a former staffer.

The Republican senator told the Las Vegas Review-Journal that he remains a productive advocate for Nevada and has more to offer.

Ensign aides did not immediately respond to messages from The Associated Press.

It has been unclear how Ensign's 2009 affair with a former campaign aide will affect his political future. Federal investigators are probing whether he broke ethics rules in an attempt to keep the affair secret.
