Daley wants investigation of Michigan oil spill


Chicago Mayor Richard Daley is demanding a criminal investigation into an oil spill that dumped a million gallons into a waterway leading to Lake Michigan.

Daley made the demand Thursday of Michigan's attorney general, arguing "oil is worse than Asian carp."

The carp remark was a reference to the filing of several lawsuits by Michigan seeking to close the O'Brien and Chicago locks. Michigan officials claim closing the locks will prevent Asian carp from overrunning the Great Lakes and decimating the fishing industry.

Illinois officials contend closing the locks would cost the local economy $4.7 billion over 20 years.

Daley noted the Great Lakes is a source of drinking water that is "very important to protect."

The oil leaked into the Kalamazoo River on Monday from a pipe belonging to Enbridge Energy Partners, a Canadian company.
