The Colorado Attorney General’s Office has filed a lawsuit against the federal government over the listing of the Gunnison sage grouse.
Last November, the grouse was listed as threatened species under the Endangered Species Act.
After the announcement, Colorado along with environmental groups and local governments threatened to sue.
On Wednesday the state filed a lawsuit in federal court against the U.S. Department of Interior and the U.S. Fish and Wildlife Service over the listing.
In a statement, Colorado Attorney General Cynthia Coffman said her office filed its complaint against the federal government 'in defense of the state’s robust efforts and $40 million investment to protect the Gunnison sage grouse.'
