TV host Jimmy Kimmel was always the lovable frat boy of late-night, often more playful than political. But Kimmel put comedy on hold when his on-air story about his son's fight for life became a call to action on healthcare; and following the Las Vegas massacre last fall, his monologue turned into an emotional call for sanity, and gun control. Kimmel talks with correspondent Tracy Smith about his road to late-night, and why he's not so bothered if viewers are upset by his heartfelt monologues. (This story originally aired on October 15, 2017.)
