Phelps and Ledecky Make It a Night to Remember in the Olympic Pool

With American fans filling the Rio Olympic swimming venue with piercing screams, the most decorated Olympian ever, and another mind-bending talent who might one day surpass him, both won gold in back-to-back races Tuesday in a stunning show of force in the water. In a matter of minutes, the U.S. phenoms Katie Ledecky and Michael Phelps took over the Games. Phelps' win brought him his 20th gold medal and, if his triumphant victory pose was any guide, a particular sense of satisfaction.
