Michael Phelps Says, "I am sorry. I promise my fans and the public it will not happen again"

“I engaged in behaviour which was regrettable and demonstrated bad judgement,” Phelps said.

“I’m 23 years old and despite the successes I’ve had in the pool, I acted in a youthful and inappropriate way, not in a manner people have come to expect from me. For this, I am sorry. I promise my fans and the public it will not happen again.”
