The Department of Justice, as I mentioned, does not develop legislation in isolation. There are many other departments and agencies that would have been involved in some fashion and had some access to the documents, to the draft legislation, because of the need and the reality of different departments contributing toward its development and the public policy framework around it.
People have varying degrees of access to it and differing levels of investment of time, in terms of its development. However, everyone who had access to the draft legislation or the development documents for the legislation would have had, and did have, the appropriate security clearances, and understood the necessities around ensuring that those security clearances and the responsibilities that go with them were followed.
