Washington should offload the land grant dispute issues to their respective state land departments.
That said that issue is entirely separate from control of the remaining lands actually in federal title.
As for Indian lands, Indian are fully capable of owning and managing their own lands in legal title as they already do in practice. The interior department should start throwing off this racist notion that they have to “hold in trust” the native american lands, and start direct transfers of that title.
Heck yes!
Why should Washington be the one screwing them when their own 'leaders' can do it closer to home!
