The AP on Thursday morning reported Attorney General Jeff Sessions was going to go after legalized marijuana, and so it came to pass. Sessions says he is rescinding a policy instituted under President Obama that had allowed legalized marijuana to flourish in six states, with more considering the move. While the drug is illegal at the federal level, Politico reports the Obama-era guidelines "effectively limited prosecutions" of entities who sold pot in accordance with their own state law. As for whether those prosecutions will now surge, who knows? "I can't sit here and say whether it will or will not lead to more marijuana prosecutions," one Justice Department official tells Politico, which notes the announcement seemed to be "deliberately vague" about its own impact. In a memo, Sessions noted that federal prosecutors should decide on their own whether to devote resources to marijuana cases based on other demands in their districts, per the AP. Read on for more on the move and one senator's very vocal pushback.
