Former US first lady Barbara Bush, who was reported to be in "failing health" over the weekend, is in "great spirits" and the family is grateful for everyone's prayers and thoughts, her granddaughter said. Proceeds from the books benefited adult and family literacy programs.
"She's a fighter. She's an enforcer", the TODAY contributor said.
Her husband, at 93, is the longest-lived United States president.
Barbara Bush, wife of former President H.W. Bush, will not seek additional medical treatment and instead will focus on "comfort care", a Bush family spokesman said Sunday. She also had a heart surgery in 2009 for a severe narrowing of her main heart valve and was hospitalised a year before that for surgery on a perforated ulcer.
At 92 years old, Bush has been suffering for some time and has been in and out of the hospital multiple times in the last year while battling with Chronic Obstructive Pulmonary Disease, or COPD, and congestive heart failure.
Barbara has also been a fierce protector and advocate for her family, most recently, helping her son, former Florida governor Jeb Bush, with his presidential campaign in 2016. The other was Abigail Adams, wife of John Adams and mother of John Quincy Adams. The couple had six children.
In retirement, former President George H.W. and Barbara Bush made Houston their home, often to the adulation of their fans whether it was sneaking a smooch on the Houston Texans kiss cam at NRG Stadium to tossing out the first pitch for the Houston Astros after President Bush broke his neck in 2015.
"She reminded me not to believe everything you read", she added.
Mr McGrath said Mrs Bush was concerned more for her family than herself.
