In a rare collision of morning-show warmth and Oval Office power, Savannah Guthrie’s family crisis has become a national drama. Nancy Guthrie, 84, disappeared from her Tucson home on Sunday, leaving behind only questions and a growing sense of dread. Local police, joined by the FBI, are treating the case as a possible abduction, scouring neighborhoods, reviewing surveillance footage and chasing every faint lead.From the White House, President Trump vowed to personally call Guthrie and offer expanded federal assistance, saying he would “sure” provide more help in the desperate search. For Guthrie, who has interviewed presidents and covered tragedies from a professional distance, the story has turned excruciatingly personal. As viewers watch her steady voice on “Today,” a nationwide manhunt unfolds off-camera, fueled by urgency, uncertainty and the fragile hope that Nancy will be found alive and brought safely home.
