OSAGE COUNTY, Oklahoma - The government has amended its lawsuit against the wind farm that's under construction in Osage County.

The government filed suit on behalf of the Osage Nation.

It's no longer trying to stop the construction because the work is too far along. Now it's focusing on the land's mineral rights.

The government claims the groups behind the wind farm didn't get the right approval and leases from the Secretary of the Interior.

The lawsuit also claims the group used minerals it dug up to build the turbines' foundations.
