LOS ANGELES — President Donald Trump said Friday that he was inclined to support a bipartisan effort in Congress to ease the U.S. ban on marijuana, a proposal that would dramatically reshape the nation’s legal landscape for pot users and businesses.

The federal ban that puts marijuana on the same level as LSD and heroin has created a conflict with more than two dozen states that have legalized pot in some form, creating a two-tiered enforcement system where cannabis can be both legal and not.

The legislation would ensure states have the right to determine the best approach to marijuana within their borders, but some U.S. restrictions would remain, including recreational sales to people under 21.

The proposal introduced Thursday has support from members of Congress from both parties, including Republican U.S. Sen. Cory Gardner of Colorado.

“I support Senator Gardner. I know exactly what he’s doing,” Trump told reporters in Washington, when asked about the legislation. “We’re looking at it. But I probably will end up supporting that, yes.”

The president’s remarks place him in conflict with his own Justice Department and U.S. Attorney General Jeff Sessions, an outspoken opponent of marijuana who lifted an Obama administration policy and freed federal prosecutors to more aggressively pursue cases in states that have legalized marijuana.

Asked about the measure in an interview with Colorado Public Radio, Sessions said, “We’ll see how far it goes and how much support there is. ... My view is clear: The federal law remains in effect nationwide, just as it does for heroin and cocaine.”

The proposal’s prospects in Congress were unclear.

Gardner, who heads the Senate Republicans’ campaign arm, is close to Senate Majority Leader Mitch McConnell. But McConnell has consistently opposed legalizing marijuana, though he calls hemp and marijuana “two entirely separate plants.”

The bill would amend the definition of marijuana in federal drug law to exclude industrial hemp. There is a growing market for marijuana’s non-intoxicating cousin, CBD oil, and farmers can make more than $100,000 an acre growing hemp plants to produce it.
