Tyler Hamilton, a teammate of cycling superstar Lance Armstrong, has told the CBS "60 Minutes" program he saw Armstrong using performance-enhancing drugs.
CBS released a portion of the Hamilton interview that will be aired Sunday. in which Hamilton told reporter Scott Pelley he saw Armstrong inject himself with drugs more than once.
Hamilton was a member of the U.S. Postal Service team for which Armstrong won the first three of his seven Tour de France titles.
"I saw it in his refrigerator, I saw him inject it more than one time," Hamilton said. "Like we all did. Like I did many, many times."
After CBS made parts of the interview public, Armstrong responded on his Twitter account.
"20-plus year career. 500 drug controls worldwide, in and out of competition. Never a failed test. I rest my case," Armstrong tweeted.
Hamilton, 40, retired from cycling in 2009 after failing an out-of-competition drug test. He was detected as having used an over-the-counter antidepressant.
