America’s best Brit John Oliver took a brief pause from skewering presidential candidates Sunday to skewer Congress’ response to the Flint lead-poisoned water crisis. As Oliver points out, the crisis is hardly Flint’s alone: 2,000 municipal water systems in all 50 states show elevated levels of lead, which can contribute to brain damage, developmental difficulties, and lower IQs in children.

In response to this disaster, Congressional Republicans Rep. Mark Meadows (NC), Rep. Tim Walberg (MI), and Rep. Jason Chaffetz (UT) all have said that is it shocking — just shocking — that federal regulators could let something like this happen in the United States.

How does something like this happen in the United States?

As Oliver explains, it happens in part because of representatives like Meadows, Walberg, and Chaffetz, who voted to cut funding for government programs dedicated to cleaning up lead pollution.“You would think that our members of Congress would be onboard with doing more to fight lead poisoning.” Oliver said. Well, they aren’t, and Congress has only done its best to cut funding to other organizations that protect public health, like the Environmental Protection Agency and the Centers for Disease Control and Prevention.
