This is an estimates committee. We know that the Afghanistan committee is looking at a particular matter. But with the exception of the possibility that he's talking about another ministry that this minister was in that time, I think it's open to this committee to ask the minister about anything that is relevant to his department.
I think it's arbitrary. The chair cannot say that he can't talk about this because another committee is discussing it. I believe the point of order is not right. This is an estimates committee, and it's a free-flowing chance to discuss things with the minister.
