He passes every single test and they bring accusations against him based on so called eyewitnesses. I want people brought down because of evidence not hearsay.

Just imagine this, he and his team was supposed to have cheated 7 straight years. Either whomever was running the tests was incompetent beyond belief or Armstrong was clean.

Travis Tygart is the head of the U.S. Anti-Doping Agency, which polices U.S. Olympic sports. Lance Armstrong won the world's most grueling event, the Tour de France, seven times. But after Tygart's investigation, Armstrong lost all of his titles. In his first interview, Tygart spoke with us for the premier of a new program, "60 Minutes Sports" on Showtime. Tygart says Armstrong was doping in his very first win at the Tour de France in 1999. The drug was EPO, which boosts endurance.

PELLEY: Was Lance Armstrong personally involved in intimidating these other riders to keep them quiet?

TYGART: He was. It was tough. All -- all these witnesses were -- were scared of the repercussions of them simply telling the truth.

PELLEY: What could Lance Armstrong do to them?

TYGART: Incinerate them.

Former teammate Levi Leipheimer felt the heat. In his sworn affidavit, he says he came to a cycling dinner after he testified to the grand jury. Leipheimer says Armstrong was there and sent Leipheimer's wife a text that read, "Run don't walk."

PELLEY: What did she take it to mean?

TYGART: It's a veiled threat. Knowing her husband had just testified, truthfully, in front of the grand jury and had told citizens of this country about this great fraud. It was a message: You better run.

PELLEY: Your investigation showed that there were personal threats made against riders who had decided to come clean. I wonder if there were any threats against you.

TYGART: There were, Scott.

PELLEY: These threats came from where?

TYGART: Emails, letters.

PELLEY: Anonymous?

TYGART: Yeah.

PELLEY: Can you remember any of the lines from the emails or the letters?

TYGART: The worst was probably putting a bullet in my head.

PELLEY: Did you take that seriously?

TYGART: Absolutely.

Cyclist Lance Armstrong once offered a large "donation" to the same agency that recently concluded he and his team had used illegal substances, causing him to be stripped of his seven Tour de Frances wins. The brazenly inappropriate gesture made to the U.S. Anti-Doping Agency is recounted by the agency's CEO Travis Tygart.

Armstrong once gave the International Cycling Union, a regulatory body for his sport, a gift of $100,000. Tygart called that "totally inappropriate." Then someone representing Armstrong tried to give USADA a large sum of money sometime in 2004. "I was stunned," he tells Pelley. "It was clear -- it was a clear conflict of interest for USADA. We had no hesitation in rejecting that offer," says Tygart, who said the amount was "in excess of $150,000." Told by Pelley that "60 Minutes" had learned it was $250,000, Tygart replies, "It was around that ballpark."

lol

Yes Yes. Lance stabbed me in the back for defending him. How despicable. The worst part isn't that he cheated since every other top cyclist was too at the time it was his adamant defense of innocence everytime someone tried to speak the truth by taking them to court or attempting to ruin the accusers' reputations. Myself and other people who attempted to defend him were betrayed and that's that. His rep is ruined. The Oprah interview didn't help anything and hopefully he fades away from the news and just lives on the wealth he amassed before the mess unraveled on him.

Bolt is clean.

Until he's proven not
