My understanding is that Ms. Couillard and Mr. Bernier were at a reception with the President of the United States, and that the Americans would expect that anybody who was part of a Canadian delegation would have been checked here, obviating the need for a check on the American side. Who would do the checking here if it was somebody taking a partner with them? Would it be you, CSIS, or who?
