As tribes gain wealth, a debate over who is "Indian enough" to be a tribal member has led to a rising tide of expulsions. According to reports, the young lady, Mia Prickett's ancestor was a leader of the Cascade Indians along the Columbia River and was one of the chiefs who signed an 1855 treaty that helped establish the Confederated Tribes of the Grand Ronde in Oregon.

But the Grand Ronde now wants to disenroll Prickett and 79 relatives, and possibly hundreds of other tribal members, because they no longer satisfy new enrollment requirements.
