Why is "Native American recognition in the United States" trending?

Wikipedia Overview

Native American recognition in the United States, for tribes, usually means being recognized by the United States federal government as a community of Indigenous people that has been in continual existence since prior to European contact, and which has a sovereign, government-to-government relationship with the Federal government of the United States.
In the United States, the Native American tribe is a fundamental unit of sovereign tribal government. This recognition comes with various rights and responsibilities. The United States recognizes the right of these tribes to self-government and supports their tribal sovereignty and self-determination. These tribes possess the right to establish the legal requirements for membership. They may form their own government, enforce laws, tax, license and regulate activities, zone, and exclude people from tribal territories. Limitations on tribal powers of self-government include the same limitations applicable to states; for example, neither tribes nor states have the power to make war, engage in foreign relations, or coin money.
