Muhammad Ali was ‘a man of eternal optimism,’ says widow Lonnie Ali

Boxing legend Muhammad Ali died in June, and now his wife Lonnie is carrying on his message with a program called “Ali 75” that calls on people to donate 75 hours of community service to commemorate what would have been the champ’s 75th birthday next January. She tells Matt Lauer she was “stunned” at the number of people who turned out for her husband’s funeral, and adds, “I hope he’s up there looking and giving me the guidance I need.”
