The architects of New York’s medical marijuana program are asking Congress to pass legislation allowing medical and recreational use programs after U.S. Attorney General Jeff Sessions announced Thursday that he is rescinding an Obama-era policy that generally kept federal law enforcement from interfering with states’ marijuana sales.

Assemblyman Richard Gottfried and state Sen. Diane Savino, both Democrats who helped craft New York’s medical marijuana program, are calling on U.S. Congress to enact legislation that would protect marijuana programs in the states that have them, which include New York and California, among others.
