Judy Woodruff discusses Colin Powell's legacy with two men who knew him well: Richard Haass was the director of policy planning at the State Department when Powell was secretary of state during the George W. Bush administration. He's now president of the Council on Foreign Relations. Michael Gordon reports on the Defense Department, and has authored several books about the U.S. military.
