Lance Armstrong: I am 'unaffected' by the USADA's report

The U.S. Anti-Doping Agency has presented its 200-page report claiming that Lance Armstrong is part of "the most sophisticated, professionalized and successful doping program that sport has ever seen," but he isn't concerned. Instead, Armstrong is spending his time focusing on things that matter to him more: family and charity.

"What am I doing tonight? Hanging with my family, unaffected, and thinking about this," he tweeted last night as the USADA made its report, including a link to a press release about how the Lance Armstrong Foundation is celebrating its 15-year anniversary with a series of events in Austin later this month.

Back in August, Armstrong had announced that he would no longer fight the doping charges that the USADA was leveling against him. The organization responded by stripping him of his seven Tour de France titles.

"There comes a point in every man's life when he has to say enough is enough," he wrote in a statement. "I have been dealing with claims that I cheated and had an unfair advantage in winning my seven Tours since 1999. The toll this has taken on my family and my work for our foundation and on me leads me to where I am today -- finished with this nonsense."
