The Trump administration plans to allow states to require drug testing for food stamps recipients, the Associated Press reported Wednesday afternoon. The report cites internal emails that show United States Department of Agriculture (USDA) officials have been preparing for an announcement since February.

If and when that announcement comes, it will be a big deal. For months, we’ve been reporting on the efforts made by conservative politicians to limit access to the Supplemental Nutrition Access Program (SNAP)—the $70-billion program which provides food assistance to over 40 million Americans. Some states, including Maine, have tried to make junk food ineligible for purchase under SNAP. And recent developments suggest that lawmakers on both sides are tangling over the program’s vast cost as farm bill negotiations heat up on Capitol Hill.

But the development reported by AP follows from a story we’ve been covering since 2017: Wisconsin Governor Scott Walker’s plan to limit SNAP access by making drug-testing a requirement for some recipients. In December, The New Food Economy’s H. Claire Brown reported on Walker’s decision to move forward with drug-testing requirements in Wisconsin, even though the United States Department of Agriculture (USDA), which funds and oversees the program nationally, had blocked him in the past. Today’s report suggests that the Trump administration will do much more than concede Walker’s request—it’s going to allow other states to do the same thing.
