A member of a parliamentary secretary's staff can be paid by the department, everyone knows that. Assistants to parliamentary secretaries are paid by the department; they are not paid from the member of Parliament's budget. This is because parliamentary secretaries have more responsibilities than a regular member of Parliament. If parliamentary secretaries used money from their own budgets to pay their assistants, there would be less money in the budgets that are set up to serve their constituents. That distinction has to be made.
