Lady Bird Johnson, the former first lady, was released from the hospital Thursday and was resting comfortably at her home, a family spokesman said.

Johnson, 94, was admitted to Seton Medical Center a week ago and treated for a low-grade fever. She remained at the hospital for observation after the fever subsided.
