WASHINGTON—President George W. Bush sustained 24 broken bones, massive internal hemorrhaging, and a severe concussion Monday after falling down the entire staircase of the 555-foot-tall Washington Monument. According to White House press secretary Dana Perino, Bush was making his weekly climb to the monument's observation floor when he lost his footing on the top step, slipped, and struck each of the obelisk's 897 stairs with the back of his skull during an uncontrolled descent to the base of the structure. President Bush is resting comfortably in Bethesda Naval Hospital.
