Former President Gerald R. Ford was responding well to treatment for pneumonia Tuesday, his fourth day in the hospital near his desert home in Riverside County, his spokeswoman said.
Ford, 92, was admitted Saturday to Eisenhower Medical Center in Rancho Mirage. It is his second hospital stay in a month and a half.
The 38th president was "doing well," according to a brief statement Tuesday from his chief of staff, Penny Circle.
Ford's condition is evaluated daily; if he continues to improve he will probably return home Thursday, said Elizabeth Wholihan, spokeswoman for Eisenhower Medical Center.
Ford suffered two small strokes in 2000 and a dizzy spell on a golf course in 2003. Last month he was in the hospital for a bad cold and medical tests.
