In 2022, the library in Vinton closed for a short period of time after employees quit for political reasons following complaints and allegations by patrons that included: the head librarian's "hiring and support for LGBTQ+ staff"; books by Jill Biden and Kamala Harris, and none about Donald Trump; "LGBTQ-themed book displays in the children’s section"; and male staff members "wearing dresses". One of the library's former directors said they had 173 books about Christian life, and seven books about "LGBT, gay or transgender" topics; another former director said some patrons "would check out the books and not return them", rather than file written complaints about the books.
