The US Government has subpoenaed the Indiana University School of Medicine to provide Lance Armstrong's medical records from his cancer treatments in 1996 to find out whether his doctors knew he was using performance-enhancing drugs.

USA Today revealed that Government lawyers made the request on 30 July, specifically asking for records of Armstrong's treatments and later donations to the school.

The request is related to the 'whistleblower' lawsuit that aims to recover millions of dollars that the US Postal Service paid to sponsor Armstrong's Tour de France-winning team from 1999 to 2004. Armstrong's victories were later annulled after he was found guilty of - and subsequently confessed to - doping throughout his career.

Discovering whether Armstrong's doctors knew that the rider had doped is likely to strengthen the argument that there had been a long-running and complex conspiracy to cover up Armstrong's doping.

A particularly notorious bone of contention has been the differing accounts of a conversation Armstrong had with one of his doctors during his treatment. Betsy Andreu, the wife of former Armstrong teammate Frankie Andreu, has insisted for years that Armstrong admitted doping to his doctors; Armstrong's lawyers say that the disgraced cyclist does not recall the admission as he was recovering from brain surgery at the time.

Armstrong's lawyers are seeking to have the subpoena quashed, arguing that Armstrong has already admitted doping prior to 1996. They called the potential release of records a violation of privacy.

The US government has also subpoenaed former sponsors Nike, Trek, Giro Sport Design and Discovery Communications in a bid to find out whether the companies were aware of Armstrong's doping during his career.

The whistleblower lawsuit was initially filed by former teammate Floyd Landis and was joined by the US government in 2013. The case is not expected to go to trial before 2016.
