The suit announced by the state's top election official and Democratic candidate for governor on Tuesday says Brnovich is "pursuing unfounded and unprecedented enforcement action against the Secretary" and "threatening the Secretary with criminal prosecution for performing her duties as the State's Chief Elections Officer."

Hobbs wants a judge to issue an injunction prohibiting the Republican attorney general from investigating or prosecuting her.

"It's disappointing that the Secretary of State tries to politicize every issue," Brnovich spokesperson Katie Conner said in a statement. "She seems more concerned with avoiding the blame than fixing the problem."
