Dealing with the Landis Whistleblower case and it appears as though Armstrong claims that Nike KNEW he was cheating, so he has subpoenaed Nike to provide communications to bolster his case.
"(Armstrong) is saying the U.S. Postal Service should have known that he was doping because of allegations, because of publicly available information that is available to all of Armstrong’s sponsors."
“The United States is entitled to develop facts surrounding what other sponsors knew. If sponsors X, Y and Z were all in the dark, that undermines Armstrong’s argument that the Postal Service should have known."
So...If Armstrong has also issued a subpoena to NIKE, he must know that such communications would IMPROVE his case, and the government is also mulling over the possibility of subpoenaing NIKE for FINACIAL information.
