U.S. skater Simon Cho says tampering with Canadian rival's skates was 'biggest mistake' (+video)

Cho failed to make the U.S. fall World Cup team, in part because of the stress this situation has caused.

"I was embarrassed and to be honest, I was mentally distracted," he said. "I feel like it took a toll on my performance."

He said the tampering charges would not have come to light had his U.S. teammates not filed a complaint against the coaches. He blames no one but himself for the possibility that he will now face punishment for tampering.

"Regretfully, I believe that telling him now would have been the best decision," said Cho. "I'm really disappointed about how this all came about, but I did what I did. ... At this point, the best thing I can do is be honest and take responsibility."
