Sen. Tom Carper wrote to acting Environmental Protection Agency Administrator Andrew Wheeler urging him to restore the American people’s trust in the agency’s mission and to consider the lessons of the past — particularly in the case of former EPA Administrator William Ruckelshaus.

Carper notes that Ruckelshaus was met with considerable skepticism when first nominated by former President Ronald Reagan to take over for scandal-ridden Anne Gorsuch. Like Ruckelshaus, Wheeler has “been granted an enormous challenge and responsibility, but an even greater opportunity.”

In the letter, Carper highlights ways Wheeler can remedy some of former Administrator Scott Pruitt’s proposals, practices and missed opportunities.
