"Sanders’ claim is false — Trump’s position has indeed changed, and in more ways than one. During an interview with a Colorado TV station in the summer of 2016, then-candidate Trump said that as president, he would not use federal power to shut down the sale of recreational cannabis in states like Colorado. “I wouldn’t do that, no,” Trump said, asked if he’d support the federal government intervening. “I think it’s up to the states, yeah. I’m a states person. I think it should be up to the states, absolutely.” Not only does Trump’s support for the DOJ’s power grab contradict his 2016 comments about thinking marijuana laws are best left “up to the states” — his decision to allow Sessions to move forward with the new policy also violates the promise he made not to interfere with states’ rights."
