The DOJ press release headline refers to the worker as a “Board of Elections Election Official” but that seems incorrect.

From an earlier HuffPost piece:

The sole U.S. citizen facing charges ― Denslo Allen Paige, a 66-year-old Walmart worker who lives in Raleigh ― told HuffPost she helped her boyfriend register in the weeks before the 2016 general election because he had been talking a lot about politics. Paige wasn’t sure if her boyfriend, a legal permanent resident, was eligible to vote, so when she filled out a voter registration form at an early voting site with him, she left the box asking about his citizenship blank. A copy of the form provided to HuffPost by the North Carolina State Board of Elections and Ethics Enforcement shows a checkmark in the “yes” box asking if the person is a U.S. citizen, but Paige insists she did not check it.

Paige said she had served as a poll worker before, and she thought someone would flag the application and send her to a separate table to inquire about her boyfriend’s citizenship status. But she said when she asked if her boyfriend could vote, a poll worker accepted the form and indicated he could cast his ballot, so she thought everything was OK.
