Roger Stone, the conservative operative and loyal Trump surrogate, has a message for the president: End the "War on Weed."

While Trump promised during the 2016 campaign to let states decide whether to legalize marijuana, his attorney general, Jeff Sessions, has espoused other ideas.

"Tens of millions of Liberty minded Americans believed [Trump] when he said this and took his message to heart, fully expecting him to end the ineffectual and wasteful War on Weed," Stone wrote in a blog post on his website on March 31.

"These voters were relieved that is, until the position of Attorney General Jeff Sessions reached the public domain," Stone said.

Stone specifically called out Sessions, who has said he's "not a fan," of the expanded use of marijuana, and has vowed to "step up enforcement," on states that have created recreational markets.

Marijuana is illegal at the federal level, though a number of states have decided to legalize it for recreational use.

The Trump administration's opposition to legalized marijuana has put the industry on edge, potentially drying up investment dollars and causing states like Colorado to lose valuable tax revenue.

"As a product of the Religious South, it is natural that AG Sessions would take the dimmest view of marijuana, but there is little room left for debate as to the origin of the marijuana prohibition laws and how they were formulated as a tool to bludgeon both the poor and minorities, the largest consumers of the formerly legal plant," Stone wrote.

"Perhaps Attorney General Sessions has forgotten his Genesis from the Old Testament," Stone continued, quoting Genesis 1:29 which states: “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food.”

Stone asserted that Sessions' views are "far from the mainstream," on marijuana, "as evidenced in the wave of legalization that washed over the United States over the past five years."

"The Trump Administration should be mindful that the recreational marijuana measures that passed in several states all passed this same way, with overwhelming popular support," Stone wrote. "This was clearly the Will of the People."

Stone went on to say that there are so many "better ways" law enforcement can be put to good use, rather than to "persecute harmless farmers and shopkeepers who are abiding by State Law."

Marijuana reform is perhaps the only area where Roger Stone, a 64-year-old Republican "dirty trickster," and John Oliver, the liberal media darling, agree: Oliver's show, "Last Week Tonight," devoted an entire segment on Sunday evening to pointing out what they see as the hypocrisy of marijuana laws in the US.

Stone will testify before the Senate Intelligence Committee over his contact with Russian officials while he was assisting Trump's campaign.
