Michael Phelps has become the first American male swimmer to qualify for five Olympics. He won the 200-meter butterfly race at the U.S. Olympic trials on Wednesday. Phelps has won 18 gold medals, more than anybody in Olympic history. He won eight gold medals in a single Olympics in 2008 in Beijing, China. But his golden image was tarnished after the 2012 London Olympics. He was arrested two times for drunk driving. He stepped away from swimming. He entered a rehabilitation program. He then returned to the pool to train for the Rio de Janeiro Olympic Games. The Games' opening ceremony is August 5. Phelps first appeared in the Olympic Games in Sydney, Australia, in 2000. He was 15 years old. Now 31, Phelps still holds three world records. He says he is happy to represent his country at the Olympic Games one more time.
