Michigan Gov. Gretchen Whitmer ordered a Canadian energy company to shut down an oil pipeline long targeted by activists despite fuel shortages brought on by the cyberattack on the nation’s largest pipeline.

“These oil pipelines in the Straits of Mackinac are a ticking timebomb, and their continued presence violates the public trust and poses a grave threat to Michigan’s environment and economy,” Whitmer’s office said in a statement about the pipeline.
