That person also said the bar for Armstrong's redemption is higher now than when the case was open, a time during which he refused to speak to investigators. The person spoke on condition of anonymity because he was discussing a confidential matter.
Armstrong, who always prized loyalty on his racing teams, now faces some very tough choices himself: whether to cooperate and name those who may have aided, abetted or helped cover up the long-time use of PEDs.
Armstrong left his hometown of Austin, where the interview was taped at a downtown hotel, and is in Hawaii. He is named as a defendant in at least two pending lawsuits, and possibly a third. The Justice Department faces a Thursday deadline on whether to join a whistle-blower lawsuit filed by former teammate Floyd Landis, who was stripped of the 2006 Tour de France title for doping.
That suit alleges Armstrong defrauded the U.S. government by repeatedly denying he used performance-enhancing drugs. Armstrong could be required to return substantial sponsorship fees and pay a hefty fine. The AP reported earlier that Justice Department officials were likely to join the lawsuit.
