Attorney General Jeff Sessions will announce today that he'll be rescinding the "Cole memo," which allowed states to legalize or decriminalize marijuana without federal interference despite federal law banning the use of marijuana.

Why it matters: Sessions is trying to create as much chaos and confusion as possible, former Director of Marijuana Coordination in Colorado Andrew Freedman tells Axios. While the federal government does not have the capacity to round up every person who uses or sells weed, Freedman pointed out, this is likely to cause a lot of confusion and could allow the federal government to apply pressure at random on states that have already legalized or are moving toward it.
