"60 MINUTES" LISTINGS FOR SUNDAY, AUG. 20

Editor's Note: These previously broadcast segments have been updated for this post-season edition.

WHO IS RAY EPPS? - Ray Epps is notorious among consumers of right-wing media as the man who initiated the Jan. 6 attack to undermine President Trump. The convoluted theory posits Epps was a secret agent of the "deep state," and it has been promoted by members of Congress. Death threats and harassment forced Epps and his wife, Robyn, to sell their Arizona ranch and go into hiding. So who is Ray Epps? Bill Whitaker spent several days with the Epps in their first television interview. Graham Messick is the producer.

THE DOMINO EFFECT - The United States is in the middle of a maternal health crisis - a woman in the U.S. is twice as likely to die from pregnancy today than her mother was a generation ago. Sharyn Alfonsi reports on the country's troubling state of maternal healthcare and visits Louisiana, where women already facing some of the country's highest maternal mortality rates are dealing with new maternal care hurdles imposed by the state's abortion ban. Ashley Velie is the producer.

YANNICK NÉZET-SÉGUIN - Correspondent Jon Wertheim interviews conductor Yannick Nézet-Séguin, music director of three major orchestras: in Philadelphia, in his hometown of Montreal and at the Metropolitan Opera in New York, which has tasked him with the bold revamping of its artistic mission. The maestro is betting new works by new composers will draw a wider audience and shore up the Met's perpetually saggy bottom line. Known for his versatility and approachability as much as his virtuosity, Nézet-Séguin tells Wertheim why he's not worried about upsetting opera traditionalists with this radical key change. Nathalie Sommer and Kaylee Tully are the producers.
