Powell became the first black Joint Chiefs chairman, retiring from the Pentagon as a four-star general. He was also the first black secretary of state. He and his wife are not only donors to the museum, but also serve on the museum council. Powell joins "CBS This Morning" to discuss black Americans' contributions to the U.S. military and more.
