He said the outpouring of support and friendship toward his wife following her death "is lifting us all up."

Their son, former President George W. Bush, told an audience at his presidential library in Dallas on Wednesday that his mother was "funny to the end." He recalled a phone conversation they had this week.

"The day before she died, I said 'Mom, I just want you know you've been a fabulous mother and I love you dearly.' And she said, 'I want you to know that you're my favorite son — on the phone,'" Bush told the audience.

"I hope you don't feel sorry for any of us, particularly me," he added. He said he was at peace because his mother was at peace. "She believes in an afterlife and was joyously looking forward to that afterlife," he said.

A tearful Laura Bush added that watching her mother-in-law taught her "how to be a first lady, and I'm so grateful for her example."

Other tributes heralded the former first lady as a warm woman of strength devoted to not only her family, but to child and adult literacy programs.

Current first lady Melania Trump, who will attend Barbara Bush's funeral on Saturday in Houston, praised her for putting "family and country above all else." Among her greatest achievements, President Donald Trump added in a statement, "was recognizing the importance of literacy as a fundamental family value that requires nurturing and protection."

Kuwaiti leader Sheikh Sabah Al Ahmad Al Sabah sent letters of condolence to the Bush family, according to the state-run news agency KUNA. The Arab nation has long celebrated George H.W. Bush for securing its freedom from Iraqi occupation in the 1991 Gulf War, and Barbara Bush was warmly welcomed when she visited Kuwait in 1993 and 2001.

Former President Barack Obama said he and former first lady Michelle Obama would always be grateful to Barbara Bush "for the generosity she showed to us throughout our time in the White House."

"But we're even more grateful for the way she lived her life — as 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," Obama said.

Former President Jimmy Carter and former first lady Rosalynn Carter called Mrs. Bush the "matriarch of a family dedicated to serving."

Barbara Bush's funeral will be held at St. Martin's Episcopal Church, which she and her husband regularly attended. The church will host a public viewing Friday. The funeral Saturday will be by invitation only.

An "uplifting celebration" of Barbara Bush's life will be held Thursday evening outside Houston City Hall. City officials encouraged people to wear blue, her favorite color, along with pearls, which became her signature neckwear jewelry. City Hall was being bathed in blue lights in her honor.
