AUSTIN, Texas – The U.S. Anti-Doping Agency said its review board made a unanimous recommendation to file formal doping charges against Lance Armstrong.

That will move the case to an arbitration hearing if Armstrong chooses to challenge, as he has indicated he would.

USADA confirmed the board’s recommendation Friday after one of its members, Clark Griffith, said he “can’t wait” to see what the arbitration panel thinks of the evidence.

Armstrong said he’s innocent. His lawyer, Robert Luskin, called the decision to formally charge Armstrong “wrong and it is baseless.”

“It is the entirely predictable product of USADA’s toxic obsession with Lance Armstrong and a process in which truth is not a priority,” Luskin said. “There is not one shred of credible evidence to support USADA’s charges and an unbroken record of more than 500 clean tests over more than a decade and a half to refute it.”

USADA said it has evidence Armstrong was taking performance-enhancing drugs while winning the Tour de France from 1999-2005.

This year’s Tour begins today.
