One of the big questions in the Flint water crisis is who knew what and when. According to the AP, the Michigan governor’s office knew more than they’ve let on—and were aware of the problems as far back as last March, when his office received an email linking Flint to an outbreak of Legionnaire’s disease.

Up until just about today, the outpouring of reporting from Flint, Mich. had forgotten the stories of the people it’s easiest to forget: undocumented immigrants. But this afternoon, several articles were published within hours of each other focusing on the specific plight faced by the undocumented in Flint.

As the country attempts to untangle exactly who is to blame for the residents of Flint, Mich. being forced to use lead-poisoned water for well over a year, the Michigan ACLU has dug up a little bit of evidence that at least absolves one important person.
