Depending on the viewpoint, former cyclist Floyd Landis is either a whistleblower seeking justice against Lance Armstrong or a bad character seeking money and revenge.

Or it can be both. But the federal government doesn’t want a jury to hear about the latter description as it pursues a $100 million civil lawsuit against Armstrong, Landis’ former cycling teammate.

The government is asking a judge to forbid issues about Landis’ character and motivation from being part of Armstrong’s trial in November. The government even said in new court filings that it does not intend to call Landis as a witness at trial.

If successful, the government could get its money back times three under the False Claims Act – nearly $100 million, with Armstrong possibly on the hook for all of it.
