Military bases removing Confederate names

The US Army removes the names of Confederate generals from bases like Fort Pickett in Virginia, named after George Pickett, who led the last rebel charge at the Battle of Gettysburg and was later charged with war crimes. The names of nine army bases will now be replaced with those of American heroes and heroines, including people of color. Fort Pickett is now Fort Barfoot (after Colonel Van Barfoot, World War II Medal of Honor recipient). CBS News National Security Correspondent David Martin tells the startling story of bases like Fort Benning (named after a founding member of the Ku Klux Klan).
