Navajo Nation president Jonathan Nez on Sunday said the pandemic has revealed disparities in the health care system across the United States, especially in Native American communities.

“I think this pandemic here has revealed some of the deficiencies in all of our health care systems throughout the country, but more so in Native American communities,” Nez told host Margaret Brennan on CBS’s “Face the Nation.”

Nez also pointed out that the Indian Health Service has been underfunded since it was established, adding that these health care professions are using the limited resources they have to fight the virus.

“Over 500 tribes throughout the country have been working hard to push back on this virus, and as many viewers may know that the Indian Health Services oversees the health care system, and the Indian Health Service has been underfunded since its inception. And so we are, the health care professionals are utilizing the limited resources that they have.
