In June 2020, when America was rocked by protests over the death of George Floyd at the hands of a Minneapolis police officer, a Facebook employee posted a message on the company’s racial-justice chat board: “Get Breitbart out of News Tab.”

News Tab is a feature that aggregates and promotes articles from various publishers, chosen by Facebook. The employee’s message included screenshots of headlines on Breitbart’s website, such as “Minneapolis Mayhem: Riots in Masks,” “Massive Looting, Buildings in Flames, Bonfires!” and “BLM Protesters Pummel Police Cars on 101.”
