Race Radio said:It is a total BS story. The guy who wrote it, Littman, has been after Novtizy for a decade. Using him as a source would be as absurd as letting Blutto write a story about LeMond
The article is clearly sensationalized to be slanted against the feds. A more objective description is that Popo was avoiding being served the subpoena - and made the mistake of daring the agents to be able to actually do so.
He told him to get out of the car, handed him a subpoena, and said he had to appear before the Lance Armstrong grand jury in Los Angeles on November 3rd.

It's doubtful the agents would have brought up Lance's name in this context, this was added by the source(s) or the journalist - which makes the story sound even less credible.
