Muir joins Elizabeth Vargas on the stalwart newsmagazine, which remains a reliable Friday night player after 34 years on the air.
ABC News President Ben Sherwood made the announcement about Muir’s new gig and Cuomo’s exit in an email to the staff. He notes that Muir’s role on “20/20″ is effective immediately but he will continue to anchor ABC’s weekend editions of “World News” and substitute for anchor Diane Sawyer as needed during the week.
As for Cuomo, Sherwood notes: “Chris has been a unique voice at the anchor desk and a valued colleague and friend. We’ll miss his energy, commitment and humor and we wish him the very best in this new venture.”
