I'll be very short.
Speaker Milliken, I think, got to the nub of the thing. Salaries and benefits are determined by the government in the budget, not by the Board of Internal Economy. That, however, may not transfer over to the question of expenditures on any particular trip or activity the member might be in. That could lead to discussion.
I agree with Speaker Milliken when he says there are some things that are sensitive enough that, in fairness to a member of Parliament, they should not be dealt with in the public domain.
