I saw you on Twitter, you been training ten weeks. [I want to] [expletive] in your [expletive] mouth. [I'm going to] slap your [expletive] mouth. [I'm going to] slap your real mother across the face (laughter). [Expletive] you, you’re still a rookie. I’ll kill you.” I wonder how far up the chain of command that this was known?
