U.S. Vice President Dick Cheney was taken to George Washington Hospital early Monday experiencing shortness of breath, a spokeswoman said. Lea Anne McBride said that doctors found his EKG unchanged and determined he was retaining fluid because of medication he was taking because of a foot problem. Cheney, who has a history of heart problems and has a pacemaker in his chest, was placed on a diuretic. McBride said the vice president was expected to be released from the hospital later Monday. A foot ailment forced Vice President Dick Cheney to use a cane on Friday, according to a report of the Associated Press.
