The Obama administration opposes closing shipping locks near Chicago to prevent Asian carp from invading the Great Lakes.
In a memo filed Tuesday, Solicitor General Elena Kagan asked the U.S. Supreme Court to reject a request by Michigan and several other states to order the locks closed.
Kagan said doing so would endanger public safety and disrupt the flow of cargo.
She said federal agencies are working with the states to keep Asian carp out of the lakes.
The voracious fish have been migrating up the Mississippi and Illinois rivers toward the Great Lakes for decades. They have infested waterways near Chicago that lead to Lake Michigan.Scientists say if the carp get into the lakes, they could disrupt the food chain and endanger the $7 billion fishery
"Working with" to no effect, Madam S.G.
In reality, this is Illinois' stalking horse. In the long run, the channel-flow should be reversed and Chicago should stop sucking Lake Michigan into the Mississippi.
