Courts have overturned federal efforts to remove the region's wolves from the endangered list. The legislation would bypass the courts.
U.S. Rep. Collin Peterson, D-Minn., says he's optimistic the provision will make it into the bill, which is expected out next week, but says it's not a done deal.
Katherine Mize, spokeswoman for Rep. Reid Ribble, R-Wis., another sponsor of the wolf provision, also says there's a good chance it could move forward.
But Wendy Keefover of the Humane Society of the United States is dismayed, saying wolves have not recovered across their historic range.
