A Minnesota congressman says a push is underway to include language in a catchall spending bill to return responsibility for managing wolf populations in the western Great Lakes region to Minnesota, Wisconsin and Michigan.

Members of Congress have introduced legislation calling for interim steps to prevent invasive Asian carp from reaching the Great Lakes through Chicago-area waterways while a permanent solution is debated.
Researchers have conducted a large-scale test of a new system to kill invasive species hiding in the ballast water of Great Lakes freighters and expect to get results back next month.
Two more water samples from near the Great Lakes have been found to contain genetic material from invasive Asian carp. Federal say the samples were taken from Chicago's Lake Calumet, where the Army Corps of Engineers reported seven other positive DNA hits earlier this week.
Former U.S. Rep. James Oberstar is getting a rare honor - a Great Lakes ship named after him. Interlake Steamship Co. is renaming a ship the Hon. James L. Oberstar after the Minnesota Democrat.
