President Donald Trump signaled he may ignore a congressional ban on interfering with state medical marijuana laws, arguing in a lengthy statement that he isn’t legally bound by a series of limits lawmakers imposed on him.

Trump issued the “signing statement” Friday after he signed a measure funding the government for the remainder of the federal fiscal year, reprising a controversial tactic former presidents George W. Bush and Barack Obama used while in office.

Trump also suggested he may ignore gender and racial preferences in some government programs as well as congressional requirements for advance notice before taking a range of foreign policy and military actions.
