According to a statement from its president, the Navajo Nation will continue its mask mandate, even as surrounding states begin to lift restrictions.
The large reservation, which is located in three different states, has witnessed a decline in cases in recent weeks.
The Navajo Nation criticized the Biden administration for banning oil and gas leasing on a large swath of New Mexico land that supported much of its community.
The tribe argued that President Joe Biden failed to properly consult it before issuing the sweeping order earlier this week. Biden and Interior Secretary Deb Haaland announced Monday that the federal government would review a new rule prohibiting oil and gas leasing within the 10-mile radius around the Chaco Culture National Historical Park in northwest New Mexico for 20 years.
