Political career 2018 election Nuvangyaoma ran to unseat incumbent Herman Honanie. Nuvangyaoma won by a "wide margin" and was sworn in on December 1, 2018. Honanie challenged the election, saying that Nuvangyaoma should have never been allowed to run for office because he had been arrested for driving under the influence in 2007. Honanie believes this violates the Hopi constitution, which disallows someone running for chairperson if they have had a felony conviction within ten years. The election board did not reject Nuvangyaoma's application to run because his name was misspelled in the court records.

Nuvangyaoma opposes the reservation being used for early COVID-19 vaccinations, stating in an interview with NBC News that “We already have the coronavirus here and I’m not going to subject my community members to be used as test models for something unless it’s safe.” After the meeting, Nuvangyaoma and other tribal leaders endorsed the Biden-Harris ticket. A few weeks later, the Hopi received a multi-million dollar grant from the Bureau of Indian Affairs to improve reservation water quality, triggered by his desire to remove arsenic from tribal water.
