White House has clarified comment that it might consider partial shutdown of Enbridge oil and natural gas line under the straits of Mackinac.

Gov. Gretchen Whitmer won't shut oil and gas pipeline but threatens to seize proceeds if owner Enbridge keeps it operating even as the energy giant gains first permits for replacement tunnel.

Citing spill risks, Gov. Gretchen Whitmer (D) set a May 13 deadline to shut down the portion of the oil and natural gas line that runs through the straits of Mackinac between the state and Ontario, but Canada opposes closure.

County judge allows restart but orders more documentation from owner Enbridge to state and federal officials on repairs to damaged east leg before it can reopen.

County judge closes damaged and undamaged legs of 67-year-old line, with June 30 date set for owner to provide update on pipe condition.
