Colin Powell

Colin Luther Powell made history when he served under President George W. Bush as the 65th United States Secretary of State (2001-2005), making him the first African American to achieve this feat. The retired U.S. Army four-star general holds a number of badges, awards and major titles from his years of military service, and is the only African-American to advise on the Joint Chiefs of Staff, acquiring the chairman position from 1989-1993. Powell was also one of the handful of Republicans to publicly endorse President Barack Obama during the 2008 presidential election.
