President Trump is attempting to fire-bomb the overinflated budget over at the corruption-plagued EPA. And it looks to be having the intended effect: draining the agency of overpaid, unnecessary Swamp Things. Because at least one of them has elected to leave, rather than stick around and watch the agency he worships be chopped down to size. Mustafa Ali, the founder of the EPA’s “environmental justice office” has resigned from the agency:

“I never saw in the past a concerted effort to roll back the positive steps that many, many people have worked on through all the previous administrations,” he said in an interview, according to the Washington Post. “I can’t be a part of anything that would hurt those [disadvantaged] communities. I just couldn’t sign off on those types of things.”

Ali said he hasn’t seen much from the Trump administration on environmental justice concerns. “I hadn’t seen any positive movement in relationship to vulnerable communities,” he said. “I hadn’t seen yet any engagement with communities with environmental justice concerns.”

So what exactly does Ali mean by “environmental justice?”
