"Promises to reveal everything he knows".
This is more FIFA stuff of course. Now, given that Jack Warner is already implicated in god knows what (bribes for votes for and from anyone and everyone, dodgy ticket sales, doing dodgy deals with Chuck Blazer, etc.), the mind boggles as to what he's about to come out with.
He's saying that he can link FIFA to the outcome of the Trinidad & Tobago elections, which is...let's say...interesting.
