Armstrong, 41, has been in discussions with the United States Anti-Doping Agency and has met with Travis Tygart, the agency’s chief executive, in an effort to mitigate the lifetime ban he received for playing a lead role in doping on his Tour-winning teams, according to one person briefed on the situation.
Armstrong is also seeking to meet with David Howman, the director general of the World Anti-Doping Agency, that person said.
Herman denied that Armstrong was talking to Tygart.
None of the people with knowledge of Armstrong’s situation wanted their names published because it would jeopardize their access to information on the matter.
Tygart declined to comment. Howman, who is on vacation in New Zealand, did not immediately respond to a phone call and an e-mail.
Armstrong has been under pressure from various fronts to come clean. Wealthy supporters of Livestrong, the charity he founded after surviving testicular cancer, have been trying to convince him to come forward so he could clear his conscience and save the organization from further damage, one person with knowledge of the situation said.
The timeline for Armstrong’s deciding whether to confess is unclear, but it is partly based on whether the United States Justice Department will join the whistle-blower lawsuit, which was filed under the False Claims Act. The sole plaintiff of that lawsuit is Floyd Landis, Armstrong’s former Postal Service teammate who was stripped of the 2006 Tour de France title for doping.
If the Justice Department also becomes a plaintiff, the case would be more formidable than if Landis pursued the case alone. Landis stands to collect up to 30 percent of any money won in the case, which could be in the millions. The team’s contract with the Postal Service from 2000 to 2004 was more than $30 million.
