In media news, the chief writer at the Fox News Channel show “Tucker Carlson Tonight” resigned Friday after CNN revealed he had written racist and sexist messages online. Blake Neff routinely posted to the website AutoAdmit using a pseudonym, attacking Asian Americans and African Americans in highly offensive language, while maintaining a thread harassing a woman with information about her personal life. In a statement, Fox News called Neff’s online comments “horrendous and deeply offensive.” Tucker Carlson has called white supremacy a “hoax”; he’s repeatedly made racist, homophobic and explicitly misogynistic remarks. In one 2006 audio recording, he’s heard attacking Iraqis as “semiliterate, primitive monkeys.”
