President Trump said he likely will support a congressional effort to end the federal ban on marijuana, a major step that would reshape the pot industry and end the threat of a Justice Department crackdown.

Trump’s remarks put him sharply at odds with Atty. Gen. Jeff Sessions on the issue. The bill in question, pushed by a bipartisan coalition, would allow states to go forward with legalization unencumbered by threats of federal prosecution.

Trump made his comments to a gaggle of reporters Friday morning just before he boarded a helicopter on his way to the G-7 summit in Canada. His remarks came the day after the bipartisan group of lawmakers proposed their measure.

One of the lead sponsors is Sen. Cory Gardner (R-Colo.), who is aligned with Trump on several issues but recently has tangled with the administration over the Justice Department’s threatened crackdowns on marijuana.

“I support Sen. Gardner,” Trump said when asked about the bill. “I know exactly what he’s doing. We’re looking at it. But I probably will end up supporting that, yes.”

The legislative proposal, which is also championed by Sen. Elizabeth Warren (D-Mass.), would reshape the legal landscape for marijuana.

California and eight other states, as well as Washington, D.C., have legalized all adult use of marijuana. An additional 20 states permit marijuana for medical use.

But even as states legalize, marijuana has remained a risky and unstable business because of federal law making it illegal. Concerns about federal law enforcement seizures have inhibited most lenders from working with marijuana businesses. And investors have also proceeded cautiously.

A lifting of the federal prohibition would bolster efforts to create uniform testing and regulatory standards for marijuana, and potentially free scientists to pursue research into the medical uses of marijuana.

Trump said he is likely to support the federal legalization effort despite a warning against it from the coalition of narcotics officer groups.
