Powell called for a review of DADT over the weekend:

Powell, as much as any congressional figure, played the foil in President Bill Clinton's efforts to follow through on a campaign promise that all citizens, regardless of sexual orientation, should be able to serve openly in the military.

Sam Nunn) have argued that political realities have evolved to the extent that the armed forces should take a closer look at the policy's purpose and effectiveness.
