New book takes a look at the first Black generals in the U.S. military

Doug Melville's new nonfiction book "Invisible Generals" takes a look at the father-and-son team who helped integrate the U.S. military and were the institution's first Black generals. Their story was ignored for decades — until Melville got the surprise of a lifetime a decade ago. Jeff Glor has more.
