Joined by free-speech advocacy group PEN America and several authors and parents, Penguin Random House filed a federal lawsuit Wednesday against the Escambia County School District and its school board, alleging they were violating the 1st Amendment by scrubbing library shelves of books based on a political or ideological disagreement with the ideas the books express.

They also allege a 14th Amendment violation citing the Equal Protection Clause, because the challenged books are disproportionately titles by nonwhite and/or LGBTQ+ authors and explore diverse stories and themes.
