Former first lady Barbara Bush was remembered as a public servant, devoted wife and mother and a tireless advocate for children as reactions poured in to her passing on Tuesday night.

Bush died at the age of 92, after reportedly being in failing health. Jim McGrath, a family spokesman, did not give a cause of death.

“As a wife, mother, grandmother, military spouse, and former First Lady, Mrs. Bush was an advocate of the American Family,” President Donald Trump said in a statement, which was dated April 17, 2017. “Amongst her greatest achievements was recognizing the importance of literacy as a fundamental family value that requires nurturing and protection. She will be long remembered for her strong devotion to country and family, both of which she served unfailingly well.“

Flags will be flown at half-staff until the day of internment across the U.S. and its territories, the White House announced Tuesday evening.

The president said that Bush was a “was an advocate of the American family“ and said his and First Lady Melania Trump‘s thoughts and prayers are with the Bush Family.

Former President Barack Obama and former First Lady Michelle Obama said in a joint statement that the former first lady and mother to President George W. Bush was a "testament to the fact that public service is an important and noble calling; as an example of the humility and decency that reflects the very best of the American spirit.”

“She’ll be remembered for passing those American values on to her children, her grandchildren, her great-grandchildren – and to the countless citizens who she and George inspired to become ‘points of light’ in service to others,” the Obamas‘ statement continued.

Bush “was a woman of unique strength and grace,” Vice President Mike Pence and his Second Lady Karen Pence said in a joint statement.

“Barbara Bush was a woman of unique strength and grace whose devotion to her family was an inspiration to every American,” the Pences’ statement said. “Mrs. Bush’s example in public life and her encouragement made a lasting impact on our family, as it did on the families of millions of Americans, and she will be missed.“

Former Vice President Joe Biden said Bush was “the picture of resilience“ and that “there was no one else quite like her.”

“Her tireless work as a champion for global literacy will be just one legacy she leaves behind,” Biden said in the statement. “The others will be her unshakeable faith, her devotion to service and her beloved family, in which she instilled that same great love of country and public service.“

Bush spent much of her adult life in Texas where her husband and former President George H.W. Bush began his political career. Texas Gov. Greg Abbott offered his condolences, saying that Barbara Bush’s “impact on Texas and our nation will forever be treasured“ and that her literacy program helped “improve the lives of those less fortunate through education.”

“Barbara Bush dedicated her life to helping others. As only the second woman in history to be both the wife and mother of U.S. presidents, Barbara had a unique and profound impact on our country,” Abbott said in a statement.

Texas Sen. John Cornyn also said in a statement that Bush’s work “promoting literacy will live on in the families she touched and young minds she helped cultivate.“

“Barbara has blessed this nation with her unwavering service, strong moral compass, and trademark sense of humor,” the Senate majority whip said in a statement.

Bush‘s public and private service were also commemorated by Texas Sen. Ted Cruz on Twitter.

“From China to Texas to DC, Barbara Bush worked on a beautiful floral needlepoint rug, stitching together changing times & geography w constant love & support for her family. Her masterpiece eventually graced the floors of the Executive Mansion, making the White House a true home,” Cruz tweeted.

During her time as Second Lady and the First Lady, Bush dedicated her life to child literacy and went on to create the Barbara Bush Foundation for Family Literacy.

Independent Women's Forum, a conservative group, commented on her work on improving lives through her foundation.

"Despite her aristocratic origins, Mrs. Bush was unpretentious, and her country loved her for her for it,” the organization releasted in a statement. “She made no pretenses about her trademark fake pearls and delighted in the 'America's grandmother' image conferred by her mane of white hair."

The Barbara Bush Foundation for Family Literacy also honored Bush on Twitter.

“We mourn the passing of Barbara Bush, who believed that the world would be a better place if more people could read, write and comprehend,” the organization wrote.

Several lawmakers also offered their condolences to the Bush family, including Democratic Sens. Tim Kaine, Kirsten Gillibrand and Bernie Sanders.
