Plans for a private funeral were set for Friday for Nancy Reagan, who died on Sunday of congestive heart failure at 94 in her Los Angeles home.
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.
To prepare for her funeral, the Ronald Reagan Presidential Library is closed, and will re-open to the public on Sunday, March 13, 2016 at 10 a.m.
As part of the official events, Mrs. Reagan will lie in repose at the Ronald Reagan Presidential Library on Wednesday, from 1 p.m. to 7 p.m. and on Thursday from 10 a.m. to 2 p.m.
Funeral services will be held at 11 a.m. on Friday and are closed to the public.
In lieu of flowers, Mrs. Reagan had asked that contributions be made to the Ronald Reagan Memorial Fund at www.reaganlibrary.com.
Flags across the country are flying at half-staff in memory of Mrs. Reagan. The White House directed federal buildings, embassies, military posts and naval vessels to lower their flags "as a mark of respect" for the former first lady. They'll remain at half-staff until she is buried.
President Barack Obama said he once had the opportunity to meet with former first lady, and Mrs. Reagan could not have been more charming and gracious to him and Michelle Obama when he came into office.
The president spoke about the former first lady on Monday after meeting with financial regulators and advisers.
Obama said the extraordinary love that she had for former President Ronald Reagan is well documented, along with the comfort and strength she provided him in hard times.
Obama said he has been lucky to have an extraordinary partner in his life as well. He knows how much she meant to the president and the country as a whole.
"He was lucky to have her, and I'm sure he would be the first to acknowledge that, so she will be missed," Obama said.
White House spokesman Josh Earnest, asked whether Obama would attend the funeral, said officials were waiting until funeral arrangements for the former first lady are settled before determining who will represent the White House at the service.
