(AP) — The Tennessee Legislative Black Caucus on Thursday called on Republican Rep. Sheila Butt to apologize for what they said was a racist Facebook post, and said she should be removed from her leadership position. In a speech on the House floor, Butt defended her comments, saying the First Amendment allows people to speak their minds. Critics say "NAAWP" has been used by white supremacist organizations and stands for the "National Association for the Advancement of White People." Butt, who is white, told The Associated Press on Wednesday that "NAAWP" stands for the "National Association of Advancement for Western Peoples," and said her post had been misinterpreted. Since Butt's Facebook post, a book she wrote has surfaced.
