When Jeff Sessions announced his decision to rescind the Cole Memo, a Department of Justice policy that protects states with legalized marijuana, many politicians from both sides of the aisle came out and criticized him. But Gary Johnson also gave an ominous warning to President Trump as well.

In an interview with theĀ Washington Examiner, the former Republican governor turned independent presidential candidate Johnson spoke about his displeasure with Sessions' decision. He then said he hoped this would damage Trump politically.

"I hope it dooms his re-election. Trump promised to leave marijuana to the states," Johnson said.

The White House said that Trump never changed his position on the issue, with spokeswoman Sarah Huckabee Sanders saying, "The president's position hasn't changed." Johnson said that is a lie.

"Trump promised this would not happen," he said.

Sessions decision on the Cole Memo, and any possible marijuana crackdown he initiates, will likely trigger a big debate for the GOP. For the last few years, the party's been divided between family values politicians who say marijuana is a gateway drug that damages the moral fiber of society and states' rights conservatives who believes issues like marijuana should be left up to the states without interference from the federal government.

Now the GOP will have to decide whether to support Sessions (and now the president, who seems to be going along with this), or leave one of the highest ranking officials in the country out to dry.

Considering how brave they've been in standing up to Trump so far this year, I think we know which route they'll take.
