Katie Couric is weighing in on how the disappearance of Savannah Guthrie's mom, Nancy Guthrie, is impacting the Today show. "This situation is tragically unprecedented, and I think it's really hard to compare anything else to what Savannah and her family are dealing with right now," Couric, 69, said in an article published by Variety on Thursday, February 26. "I do think morning shows are living, breathing organisms, and when something happens to a member of these very close-knit teams, it is devastating." Couric worked at NBC's Today from 1991 to 2006 before moving to CBS.
