This week "Sunday Morning," hosted by Jane Pauley, features Rita Braver's cover story in which she revisits three transgender youth to see how their lives have progressed since our initial story with them five years ago. Plus: Tracy Smith talks with Sir Elton John about his new autobiography, "Me"; Michelle Miller profiles "Law & Order: Special Victims Unit" star Mariska Hargitay; Nicholas Thompson, the editor-in-chief of Wired, talks with Democratic presidential candidate Andrew Yang; Scott Simon, of NPR, talks with Chicago White Sox play-by-play announcer Jason Benetti, who has cerebral palsy; and Luke Burbank visits a small park in Indianapolis in an unusual location: on the median of a busy interstate highway.
