Savannah Guthrie emotionally pleaded for the public to help find her missing mother, Nancy Guthrie, one week after she was abducted from her Arizona home. “I wanted to come on and just share a few thoughts as we enter into another week of this nightmare,” the “Today” host said via an Instagram video Monday. The TV personality thanked everyone for the “love” and “prayers” she says have been felt by herself, her brother, Camron, her sister, Anne, and even her mom.
