The committee can request these documents, but if the person or the authority responsible for these documents has concerns about the security issues with regard to the committee, it's going to be up to the committee to decide what it wants to do, exactly what you guys want to do with this concern.
There are several options out there that are available to the committee. There's the possibility of considering these documents in an in camera session, for instance, or maybe specific distribution to the committee, with numbered copies, and at the end of the meeting the clerk would gather all the documents once again. The committee also can decide to treat the documents as confidential pieces of information, which means that at the end of the session they will be kept confidential for 30 years before someone will access it.
Basically, it's going to be up to the committee to decide what it wants to do with the concern that has been communicated to the committee.
