Former Senator Sam Nunn spent the last week traveling in Russia with Senator Richard Lugar, and gained publicity from the trip. Here is an Atlanta Journal-Constitution interview with him, in which he repeats his suggestion that the U.S. talk to Iran. On the subject of running for president outside the two major parties, he merely repeated what he has said before: “It’s possible but not probable. At this stage I am completely consumed with my present activities and not making presidential moves.”
