US President Donald Trump contacted “Today” show host Savannah Guthrie to offer his support as law enforcement agencies continue searching for her missing mother, 84-year-old Nancy Guthrie, in Arizona. The White House confirmed that Trump called Guthrie on Wednesday, expressing sympathy and pledging that all available federal resources would be used in the investigation.

Nancy Guthrie was last seen Saturday night after being dropped off at her Tucson home. Police believe she was abducted later that evening, and the case was officially declared a suspected crime earlier this week. Authorities reported signs of forced entry and said they do not believe she left voluntarily.

The search is being led by the Pima County Sheriff’s Office with assistance from the FBI, which is analyzing digital and cell tower data. Investigators cited Nancy Guthrie’s limited mobility and health conditions, including heart issues and a pacemaker, as major concerns.

As national attention grows, Savannah Guthrie has stepped away from her on-air duties to be with her family, while officials continue to follow leads and review possible ransom notes submitted to authorities.
