i knew the truth would come out. and the only reason he finally admits it is because weintraub was recently caught on camera (weintraub didn't know he was being filmed at the time) admitting that kenny did in fact send BJ a text about GSP greasing. kenny probably saw that video online and decided to finally admit it (or partly admit it, at least)
kenny should have claimed from the start that he sent BJ a text about huerta greasing, instead of saying that he never sent BJ a text about anything at all. now he is the one who looks like a liar.
