MINNEAPOLIS — Several members of Congress are preparing legislation to take gray wolves in Minnesota, Wisconsin, Michigan and Wyoming off the endangered list in an attempt to undo court decisions that have blocked the states from allowing wolf hunting and trapping for sport and predator control.

U.S. Rep. Reid Ribble, R-Wis., is leading the effort, his office confirmed Tuesday. Co-sponsors include U.S. Reps. Collin Peterson, D-Minn., Dan Benishek, R-Mich., and Cynthia Lummis, R-Wyo.

“I am pursuing a bipartisan legislative fix that will allow the Great Lakes states to continue the effective work they are doing in managing wolf populations without tying the hands of the Fish and Wildlife Service or undermining the Endangered Species Act,” Ribble said in a statement.

Ribble spokeswoman Katherine Mize said he hasn’t decided exactly when to introduce the bill, but the lawmakers are circulating a draft.

The legislation is in response to a ruling by a federal judge in Washington, D.C., last month that threw out an Obama administration decision to “delist” wolves in the western Great Lakes region.
