Nancy Reagan dies at 94

Former first lady Nancy Reagan died Sunday at her Los Angeles home. She was 94.

The cause of death was congestive heart failure.

Reagan is said to have unabashedly put Ronald Reagan at the center of her life but became a political figure in her own right.

“Without Nancy, there would have been no Gov. Reagan, no President Reagan,” said Michael Deaver, a longtime aide and close friend of the Reagans who died in 2007.

President Barack Obama said Nancy Reagan "redefined the role" of the first lady. He then spoke of the couple's trying times toward the end of the former president's life.

“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," Obama said.
