(Newberg, OR) -- The Newberg School District is expected to reverse its ban on Black Lives Matter and LGBTQ Pride flags in school buildings following a threat of legal action from the ACLU. KATU-TV says that's according to a meeting agenda for a special school board meeting being held by the district tonight. The ACLU of Oregon issued a statement Monday 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.
