Former U.S. President Gerald Ford was undergoing treatment for pneumonia Monday at the same facility where he was briefly hospitalized a month ago, his chief of staff said. He was said to be doing well. Ford, 92, was admitted Saturday to Eisenhower Medical Center near his home in Rancho Mirage in Southern California, Penny Circle said. "Based on his age it is prudent for his initial course of treatment - IV antibiotics - to be done at the hospital," Circle told The Associated Press. Ford was expected to be released from the hospital Wednesday or Thursday, she said. "He's doing very well," she said.
