In a joint statement released by the White House, President Barack Obama and first lady Michelle Obama paid tribute to the late Nancy Reagan and extended their condolences to her family.

The statement read in part, “Our former First Lady redefined the role in her time here. 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.”

The Obamas continued, “We offer our sincere condolences to their children, Patti, Ron, and Michael, and to their grandchildren. And we remain grateful for Nancy Reagan’s life, thankful for her guidance, and prayerful that she and her beloved husband are together again.”

Reagan died Sunday at the age of 94, and celebrities like Arnold Schwarzenegger and Elizabeth Banks, as well as politicians and presidential candidates, have paid tribute.

“Nancy Reagan once wrote that nothing could prepare you for living in the White House,” the Obamas said in the statement. “She was right, of course. But we had a head start, because we were fortunate to benefit from her proud example, and her warm and generous advice.”
