Michigan drops oil pipeline suit, refocuses on separate case

Michigan Gov. Gretchen Whitmer abandoned a lawsuit Tuesday aimed at shutting down an oil pipeline that runs through part of the Great Lakes but said the state would continue pursuing a separate case with the same goal.

Whitmer revoked the 1953 easement for that segment last year, agreeing with Indigenous tribes, environmentalists and tourist businesses that it risks a devastating spill. State Attorney General Dana Nessel filed a state...
