(Newberg, OR)  --  The American Civil Liberties Union is threatening legal action against the Newberg School District for voting to ban Black Lives Matter and LGBTQ Pride flags from school buildings.  The ACLU of Oregon issued a statement yesterday demanding an immediate retraction of the ban.  The ACLU says the flags constitute protected speech and that schools are legally obligated to ensure that Black and LGBTQ students and employees are welcomed.  The Newberg School Board voted 4 to 3 to enact the ban earlier this month, prompting criticism from the ACLU, the teacher's union and the state legislature's Black, Indigenous, People of Color Caucus.
