Sam Nunn was a US senator who wanted to buy surplus nuclear weapons from Russia, rather than risk them wandering off. He was unable to convince the rest of the government to pay for it, but he was able to convince the government to let Buffet and Turner pay for it. He has since decided that he can do more to save the world outside of government.
Added: But, he was rumored to be Secretary of Defense under Gore. So he thought some positions of government were more useful than others.
