I would be interested in seeing more information about that.
I believe that Sen Coburn made a statement to the steps to be taken in that regards.
But, all they would need to do is go through their legislatures and claim that land per the US Constitution, Art 1 Sec 8 Clause 17, and declare that land theirs since the Federal agencies have failed in the management of the land and no longer hold the trust, of the state citizens, to manage that land.
I have to get out my law book on trusts again. But I do know this, that if a trust is mismanaged, those that manage that trust can be dismissed and the trust no longer is held.
