Lance Armstrong spoke to investigators about doping in May as they dig into cycling's past association with the practice, reports the Associated Press.
Armstrong's attorney Elliot Peters said Armstrong spoke to investigators for seven hours on May 22 in a hotel outside Dulles Airport in Washington, D.C.
Armstrong, 42, was stripped of his seven Tour de France titles over his use of performance-enhancing drugs after years of denying taking anything to help in his dominance of the sport.
"They asked him about everything ... If you made a list of all the questions people would want to ask about Lance and his activities in cycling and everything else, those were the questions that were asked and answered," Peters said.
The investigation centers on the International Cycling Union's handling of doping in the late 1990s and early 2000s, trying to determine if former officials with the sport's governing body helped in Armstrong's doping.
