Barbara Bush, 92, is said to be in "failing health", and is undergoing comfort care after deciding not to seek further medical treatment.

Texas Governor Greg Abbott issued a statement saying, "Barbara has a character that is as big, inspiring, and iconic as Texas. Cecilia and I ask all Texans in joining us in praying for Barbara and the entire Bush family at this time."

WFAA reports a family spokesperson made the announcement on Sunday. Barbara Bush served as the first lady from 1989 to 1993 while her husband was President. The couple have lived in Houston since they left office.

Both Barbara and George Bush are 93 years old.
