Deadline looming in Engridge battle

There's a midnight deadline for Enbridge to shut down its Line 5 pipeline in the Straits of Mackinac. The company says they have no intention of shutting down. Enbridge says only the federal government has the authority to order a shutdown. The Canadian company and its supporters say doing so would risk the same fuel disruptions experienced on the East Coast following a cyberattack against a pipeline there. Opponents say the two situations are different and accuse Enbridge of flouting the law.
