On Wednesday, Gardner met with Attorney General Jeff Sessions over the decision to revoke an Obama-era policy at the DOJ to not enforce marijuana as a priority.

Gardner has vowed to block all DOJ nominees from confirmation until Sessions relinquishes on marijuana enforcement. Gardner says Sessions assured him marijuana would not become a priority before Sessions was confirmed by the Senate.

Denver-based U.S. Attorney Bob Troyer has indicated that he will not change the way his office treats marijuana.

“I don’t think this will slow (legalization) down at all,” said Orens. “States will continue to move forward.
