Lance Armstrong recently admitted to doping on Oprah, but according to USADA CEO Travis Tygart he's still not telling the truth on many key issues. On last night's episode of 60 Minutes, Tygart sat down with Scott Pelly to point out contradictions Armstrong made in his confession to Oprah.

Some key points -
[*]Armstrong raced clean during his 2009 and 2010 comebacks...

According to the USADA's reasoned decision to ban Armstrong, his blood levels during the comeback years of 2009 and 2010 all but point to blood doping. During Armstrong's interview with Oprah however, Lance made claims he stopped doping after his 2005 Tour de France and the comeback was raced completely clean.

Tygart says that Armstrong's claims were "just contrary to the evidence."

"The evidence is clear. His blood tests in 2009, 2010, expert reports based on the variation of his blood values from those tests, [make it a] one-to-a-million chance that it was due to something other than doping."

[*]Armstrong offered USADA a $250,000 "donation"

When Oprah asked Lance if he or one of his team offered USADA money in an attempt to pay off USADA in a bid to quash the allegations, he denied the claim.

Tygart tells Pelly that's not true, "I received a phone call from one of his closest associates and they offered us the money,"

"Lance wants to make a financial donation to USADA." Tygart claims one of Armstrong's closest representatives made the call and offer, but would not elaborate on who, pending a Federal Investigation.

Travis Tygart also told 60 Minutes in his interview that the United States Anti-Doping Agency has sent Armstrong a letter informing the disgraced cyclist he has until February 6th to tell the truth under oath in a possible lessening of his lifetime ban on sports. If he does not come in and provide a sworn testimony, his ban would forever be irreversible.
