Require agencies to change their falsehoods under the "Information Quality Act" 

Congress passed the Information Quality Act to require government agencies to tell the truth, and to respond and correct their facts when citizens point out falsehoods.

But agencies get stuck in their lies and decline to follow this law. In particular, there's a current court case against HHS regarding whether marijuana has any legitimate use in medicine. The agency has argued to the court that despite the Act, they have no obligation to revise facts that they publish, and that citizens have no standing to take an agency to court to make it correct its lies. The District Court bought this argument; the case is now in the 9th Circuit.

The Obama administration should by Executive Order require agencies to correct their falsehoods, and to submit to the jurisdiction of the courts and the standing of requesters in doing so. And if the courts determine that the IQA does not provide sufficient jurisdiction for a lawsuit, it should be revised by Congress to have enough teeth that lying agencies can be brought, kicking and screaming, to the truth.
