U.S. Rep. Sam Farr (D-CA) — along with nine cosponsors — introduced
the "Steve McWilliams Truth in Trials Act" in the U.S. House of
Representatives. The bill would end the federal government's gag order
on medical marijuana defendants in federal court by ensuring that they
can introduce evidence that their marijuana-related activity was for a
valid medical purpose under state law.
