There have been and continue to have lawsuits over incomes from various contracts issued by the Fed’s on Indian lands alleging sweetheart deals, failure to pay lease incomes to the tribes, etc.
Oh come on.
Who do you think swiped that money in the first place?
It goes to BIA offices and tribal leaders and disappears.
Somehow you see this as the fault of evil non-Indian swindlers?
The tribal heads take their cut and don’t give a damn where the rest of it goes; then taxpayers are told to pay it out again.
Not every tribal government is corrupt. But most are, and their own members pay for it, as do taxpayers everywhere.
