Former first lady Nancy Reagan, who joined her husband on a storybook journey from Hollywood to the White House, died Sunday.
She was 94.
Reagan died at her home in Los Angeles of congestive heart failure, according to her spokeswoman, Joanne Drake of the Ronald Reagan Presidential Library.
"Mrs. Reagan will be buried at the Ronald Reagan Presidential Library in Simi Valley, California, next to her husband, Ronald Wilson Reagan, who died on June 5, 2004. Prior to the funeral service, there will be an opportunity for members of the public to pay their respects at the library," Drake said in a statement.
The former first lady requested that contributions be made to the Ronald Reagan Presidential Library and Foundation in lieu of flowers, the statement said.
In a statement, President Barack Obama thanked Reagan for her "warm and generous advice."
"Our former First Lady redefined the role in her time here," he continued. "Later, in her long goodbye with President Reagan, she became a voice on behalf of millions of families going through the depleting, aching reality of Alzheimer's, and took on a new role, as advocate, on behalf of treatments that hold the potential and the promise to improve and save lives.
"We offer our sincere condolences to their children, Patti, Ron, and Michael, and to their grandchildren. "
Republican leaders also paid tribute.
"With the passing of Nancy Reagan, we say a final goodbye to the days of Ronald Reagan," wrote 2012 GOP presidential nominee Mitt Romney on Facebook. "With charm, grace, and a passion for America, this couple reminded us of the greatness and the endurance of the American experiment. ... God and Ronnie have finally welcomed a choice soul home."
