Bidding farewell to "60 Minutes" after 20 years, Anderson Cooper said balancing the show with CNN anchoring and raising his sons was "challenging."

Sunday's episode of 60 Minutes saw Anderson Cooper sign off from the news magazine after 20 years.

“There’s very few things that have been around for as long as 60 Minutes has and [have been able to] maintain the quality that it has,” Cooper said, per Variety.
