Lance Armstrong, seven-time Tour de France champion, faces new allegations from a teammate that he failed a 2001 drug test, and a grand jury probe. He has long said, 'Where's the proof?'
Now, Armstrong faces another steep challenge: an onslaught of allegations by some past colleagues that he used performance-enhancing drugs to win the grueling race. Just to make the challenge even more difficult, a federal grand jury in Los Angeles has been investigating to see if any fraud was committed.
“It’s a whole series of concentric circles, and it certainly seems like the circles are closing in on Lance,” says Patrick Rishe, an economist at Webster University and director of Sportsimpacts, a sports research firm. “With all these people coming forward, you just have to wonder.”
