The house discussed several bills concerning Native American rights this week:

H.R.2074 - Indian Buffalo Management Act

H.R.2930 - Safeguard Tribal Objects of Patrimony Act of 2021
https://www.congress.gov/bill/117th-congress/house-bill/2930/text/ih (passed the house & sent to the senate)

H.R.4352 - To amend the Act of June 18, 1934, to reaffirm the authority of the Secretary of the Interior to take land into trust for Indian Tribes, and for other purposes.

I'm tentatively in favor of the first two (the third does clarifies some technical language but does...basically nothing else afaik) tho I'll do more research before I call my reps
