Summary
The protection of classified national security and other controlled information is of concern not only to the executive branch, which determines what information is to be safeguarded for the most part,1 but also to Congress, which uses such information in fulfilling its constitutional responsibilities. As a result, Congress has established procedures and mechanisms to protect controlled information in its custody. These arrangements, however, differ between the House and the Senate and among panels in each chamber. The Senate, for instance, has established an Office of Senate Security to centralize responsibility for personnel and information security, whereas the House has not created a chamber-wide counterpart. Proposals to change the system, some of which could prove controversial or costly, usually seek to set uniform standards or increase requirements for access. This report will be updated as conditions require.
