Jeff Sessions' former Senate colleagues, dismayed at Donald Trump's humilating tweets and comments about him, are rallying to his defense, urging the president to stop castigating an attorney general he describes as a "beleaguered" and "very weak" disappointment. But their solidarity with Sessions goes only so far, as demonstrated by today's vote on a spending rider that blocks Justice Department interference with medical marijuana laws.

The Senate Appropriations Committee approved the rider, known as the Rohrabacher-Farr amendment, by a voice vote, indicating that it was not controversial among the panel's members, who include 16 Republicans. The committee thereby rejected a personal plea by Sessions to let the amendment lapse.

"I write to renew the Department of Justice's opposition to the inclusion of language in any appropriations legislation that would prohibit the use of Department of Justice funds or in any way inhibit its authority to enforce the Controlled Substances Act," Sessions said in a May 1 letter to Senate and House leaders. "I believe it would be unwise to restrict the discretion of the Department to fund particular prosecutions, particularly in the midst of an historic drug epidemic and potentially long-term uptick in violent crime."

Evidently Sessions' former colleagues found that logic, tying medical marijuana to violence and heroin use, unpersuasive. The committee's approval of the rider Sessions opposes, which was first enacted in 2014 and has been renewed each year since then, sets the stage for its inclusion in the final bill providing funding for the Justice Department.

"This vote is not only a blow against an outdated Reefer Madness mindset," says Marijuana Majority Chairman Tom Angell, who first reported Sessions' letter. "It is a personal rebuke to Jeff Sessions. The attorney general, in contravention of President Trump's campaign pledges and of public opinion, specifically asked Congress to give him the power to arrest and prosecute medical marijuana patients and providers who are following state laws. A bipartisan group of his former Senate colleagues just said no. A majority of states now allow medical cannabis, and we will not allow drug warriors in the Justice Department to roll back the clock. The war on marijuana is ending, even if Jeff Sessions doesn't realize it yet."

Two weeks ago, the same Senate committee, by a vote of 24 to 7, approved an amendment that would have permitted Veterans Health Administration doctors to recommend marijuana as a treatment in states that allow medical use. Last year that amendment passed the Senate and House by wide margins but did not end up in the final appropriations bill. Yesterday the House Rules Committee voted to keep the rider from proceeding to a floor vote.
