I think there's a link or something missing here - I believe you're referring to this:
The mayor of Hudson, Ohio wants school board members to resign over supplemental course material for students from a "642 Things to Write About" book.

Within the education field, this has happened before where sources are not properly vetted and this is definitely a pretty egregious offense of that. What I'm not clear on is how the school board are Democrats or showing a liberal front as political affiliation was never mentioned.
