engages them in all areas of Federal law. Their clients include Senators, Senate committees and

The Offices of Legislative Counsel
The Offices of Legislative Counsel (OLC) are non-partisan offices in each chamber that provide technical expertise in legislative drafting to members and committees. They prepare bill mark-ups and verify proposed language for consistency with the rest of the U.S. Code. These attorneys do not set the policy of the legislation on which they work. In fact, an attorney in the OLC may draft a bill for introduction and draft all of the competing amendments offered to that bill. The attorney is concerned with the legislative policy behind the bill only for the purpose of ensuring that the draft accurately reflects that policy. Because of the nonpartisan nature of the OLC, current substantial political activity may disqualify potential employees from gaining positions. Counsel in these offices will meet with members and their staffs to discuss legislative proposals; attend committee meetings; discuss the legislation with their counterparts in the House, Senate, or Executive Branch; review the Congressional Record and other materials regarding other matters in the subject area; attend floor consideration; research related prior legislation; and draft bills and amendments.
