Former US First Lady Barbara Bush dies at 92.

Former US first lady Barbara Bush died Tuesday at the age of 92, triggering an outpouring of praise for the matriarch of a Republican family once at the apex of American politics.

“A former first lady of the United States of America and relentless proponent of family literacy, Barbara Pierce Bush passed away Tuesday, April 17, 2018 at the age of 92,” said a statement from the office of George H.W. Bush. They were married for 73 years.

Barbara Bush has long been considered the rock at the center of one of America’s most prominent political families, as the wife of a president and the mother to another — George W. Bush — and to Jeb Bush, a former Florida governor and onetime presidential aspirant.
