As I said before, it can be a very partisan process. Things that are highly controversial are often subject to very partisan questioning. You often get disorderly events in committees, in which non-government senators are seeking to expose the failings of particular projects and the government senators are trying to defend them, and they become a bit heated about them. That's the way free politics work: things are controversial and they get seriously probed. Senators defending their government and defending the programs is all part of the accountability process. It all adds to accountability.
I say to public servants, this is a tough process; this is something you as public servants have to get used to. You have to jump into the swamp of politics, as it were, along with all the crocodiles and perform your tasks in that setting. If you can do that, you're good public servants.
