When reports detailed the Trump administration’s planned budget cuts to the Environmental Protection Agency leaked earlier this month, it seemed like Mustafa Ali was a marked man.

Ali, an agency vet who helped lead the EPA’s environmental justice efforts for 24 years, oversaw an office that was going to lose close to 80 percent of its funding under Trump’s plan. That proposal sent a clear signal that the Trump White House wasn’t all that interested in helping vulnerable communities living amid environmental contamination.

Within a week of the budget leak, new EPA Administrator Scott Pruitt had a three-page resignation letter from Ali on his desk. It was gracious in tone, encouraging Pruitt to seize his “once-in-a-lifetime opportunity to bring people together,” and beseeched him to protect initiatives like the Collaborative Problem-Solving Model and Environmental Justice Small Grants Program that had helped more than 1,400 communities, according to Ali.
