EXCLUSIVE — Sen. Joni Ernst (R-IA) is demanding the Environmental Protection Agency prevent a “Flint water crisis” from occurring inside federal buildings, arguing telework and the agency’s focus on climate policies led to unsafe drinking water.

In a letter sent Wednesday to EPA Administrator Michael Regan and provided exclusively to the Washington Examiner, the Iowa senator pointed to several reports from the General Services Administration Office of Inspector General. The reports found that water in several federal buildings, including employee child care centers, was contaminated with “dangerous toxins.”
