Twitter's Chief Executive Jack Dorsey apologized on Thursday after the microblogging service let through an ad promoting a white supremacist group.
"We made a mistake here and we apologize. Our automated system allowed an ad promoting hate. Against our policy. We did a retro and fixed," Dorsey tweeted(external link).
The ad titled "New Article: The United States Was Founded as a White People's Republic on NEW ORDER website" showed eight white children in a field. It was tweeted from an account with the handle @NEW_ORDER_1488.
