I notice they did not mention any advantages she obtained from claiming native American ancestry.
Getting on board with a staff already filled with Caucasians (diversity hiree) would be a start. Advertising that they have a Native American teaching in the program and thus not likely to let her go if she had shortcomings (and maybe even offered inducements to stay if she signaled an intent to leave) would be another. Resident Expert status or anything involving Native Americans and all the academic/scholarly prestige that goes with it—just for having "high cheekbones!"
