To start with, you could have a conversation with those who were in the room. You could have a conversation with all the different parties and see whether there is any willingness to come clean among members of this committee. You could talk to the journalists who reported on this story. There are a number of things you should undertake.
Certainly, it is important that you make it extraordinarily clear to this committee that it is not just unfortunate. It is against the rules of this committee. It harms all of us—even those who leaked that information—when we can't trust that other parties will not go to the media. I would certainly like you to say something publicly to admonish the behaviour that has led to this leak.
