Savannah Guthrie, co-anchor of "TODAY" on the NBC morning show, will return to work on April 6 as investigators continue to search for her 84-year-old mother, Nancy Guthrie. This is Guthrie's first interview since her mother went missing in February. She stated that returning to work is "part of my purpose right now" and that her religious faith is how she stays connected to her mom. The case is being investigated as a possible kidnapping or abduction, but no motive has been disclosed.
