新密歇根州州长格蕾琴·惠特默（Gretchen Whitmer）（D）已要求总检察长达娜·内塞尔（Dana Nessel（D））就麦基诺海峡下的恩布里奇5号线管道的立法是否存在，并形成新的麦基诺海峡走廊授权的立法是宪法的。Outgoing Gov. Rick Snyder (R) signed a bill passed by the state’s Republican-led legislature Dec. 12 that approved construction and operation of a utility tunnel in the straits that would house a replacement for a segment of the pipeline and create a new authority to oversee the project.
