Donald Rumsfeld is both the youngest and the oldest person to have turned in the SecDef position. The traces of Rumsfeld's Republican connections lead back to 1958, when he served as an assistant to Congressman Dave Dennison of Ohio. He has since held other high-profile positions like being a four-term U.S. Congressman from Illinois (1962–1969), Director of the Office of Economic Opportunity (1969–1970), Counselor to the President Richard Nixon (1969–1973), the United States Permanent Representative to NATO (1973–1974), as well as White House Chief of Staff (1974–1975). As for his latest tenure as SecDef, it has been considered to be one of the most pivotal in recent history since Rumsfeld was one of the key people in planning the United States' response to the September 11, 2001 attacks, which included two wars, one in Afghanistan and one in Iraq. Even though he was adored by media for his outspokenness as the wars lingered Rumsfeld gave in his resignation in late 2006. Soon after, he published his autobiography titled Known and Unknown: A Memoir.
