(born September 8, 1938) is an American politician who served as a United States Senator from Georgia (1972 – 1997) as a member of the Democratic Party.
After leaving Congress, Nunn co-founded the Nuclear Threat Initiative (NTI), a charitable organization working to prevent catastrophic attacks with nuclear, biological, and chemical weapons, for which he is presently co-chairman.
His political experience and credentials on national defense reportedly earned him consideration as a potential running mate for presidential candidates John Kerry (2004) and Barack Obama (2008) after they became their party's nominees.
