Here is the latest news story and video (shown below which is different) from WJLA, the ABC affiliate in Washington, DC regarding Keith Brown's resignation. It features interviews with some former players who said that his use of profanity was the norm.
Also here are the audio snippets from WJLA's Soundcloud page (language is edited) of Coach Brown who talks about taking issue about "being tested" and another one where he told off a player saying that she is a "grown God-d***ed woman" and eventually called her a "dumb f***" after the player punched a wall out of frustration according to the WJLA article.
We also have to note that in the article there were players on the Georgetown team who were supportive of Brown and believed that his coaching style was not abusive.
