The Trump administration is abandoning a Justice Department threat to crack down on recreational marijuana in states where it is legal, a move that could enable cannabis businesses in California and other states that have legalized pot to operate without fear of federal raids and prosecution.

President Trump personally directed the abrupt retreat, which came at the behest of Republican Sen. Cory Gardner of Colorado. White House officials confirmed the policy shift Friday. Trump did not inform Atty. Gen. Jeff Sessions in advance of the change in policy, an almost unheard of undermining of a Cabinet official.
