"An analysis of [EPA] enforcement data by The New York Times shows that the administration has adopted a more lenient approach than the previous two administrations — Democratic and Republican — toward polluters," Eric Lipton and Danielle Ivory write on the front page:

• "The Times built a database of civil cases filed at the E.P.A. during the Trump, Obama and Bush administrations. During the first nine months under [Administrator Scott] Pruitt's leadership, the E.P.A. started about 1,900 cases, about one-third fewer than the number under President Barack Obama's first E.P.A. director and about one-quarter fewer than under President George W. Bush's over the same time period."
