Atlanta ? Civil rights matriarch Coretta Scott King was in fair condition Tuesday after being hospitalized for an unspecified condition, a hospital official said.

King, 78, the widow of the Rev. Martin Luther King Jr., went to an emergency room Tuesday morning and was resting comfortably later in the day, said Piedmont Hospital spokeswoman Diana Lewis.

Lewis would not elaborate on the reason for the hospitalization, but said King would spend the night at the hospital for observation.

Lewis said the King family was expected to release a statement today.

King has canceled recent public appearances, raising concerns about her health.

At a ceremony paying tribute to the King family at the Georgia State Capitol on June 30, her son Martin Luther King III said his mother was “doing well” and was only abiding by her doctor’s orders to limit her activities.
