States challenge rule aimed at reducing drifting pollution
7m 10s
The Supreme Court heard arguments in a major environmental case over a rule that requires states to stop their air pollution from drifting over to neighboring states. Three states, led by Ohio, are claiming the rule is too costly and they’re asking the court to block the so-called “good neighbor” policy. William Brangham discussed the case with Coral Davenport of The New York Times.
