In an age where superlative sports performances automatically spark suspicion, Michael Phelps insisted on Friday that his record-setting swimming exploits are achieved fairly.
"Anyone can say whatever they want, I know, for me, I am clean," Phelps said after winning his sixth swimming gold medal of the Beijing Games.
Phelps is just two triumphs away from surpassing Mark Spitz's record of seven golds at one game, set in Munich in 1972.
His 12 career golds to date, including six from the Athens Games, are the most of any Olympian in any sport.
To underscore his supremacy, Phelps has captured all six of his golds in the Water Cube with world records.
Phelps's phenomenal effort has made him the story of the Games.
