The injury forced Reagan, 90, to miss a speech by US Representative Paul Ryan at the Ronald Reagan Presidential Library on Tuesday, spokeswoman Joanne Drake said in a statement emailed to Reuters. ”Weeks ago Mrs. Reagan took a fall at her home and fractured a number of ribs,” Drake said. She said Reagan was “adding a few appointments back to her schedule” but has been advised by her doctor not to attend large events too far from home yet. “She personally invited Congressman Paul Ryan to speak at the Reagan Library and really wanted to be there, but sent her apologies to him early yesterday,” Drake said. Reagan, who became first lady in 1981 when Ronald Reagan was elected president, was hospitalized in 2008 with fractures to her pelvis and lower spine suffered in a fall. Her husband was diagnosed with Alzheimer’s disease in the 1990s and she devoted much of her time to caring for him until his death in 2004.
