For the third successive Congress, we are releasing a table of authorities that summarizes the investigative powers of each House and Senate committee. We believe that understanding a committee’s investigative powers is crucial to successfully navigating a congressional investigation.
Congressional committees have the power to issue subpoenas to compel witnesses to produce documents, testify at committee hearings, and, in some cases, appear for depositions. Although the Fifth Amendment applies in the context of a congressional investigation, standing committees nevertheless may appeal to the full House or Senate to hold in contempt any witness who refuses to appear, answer questions, or produce documents. Congressional contempt authority may take one of three forms: inherent, civil, or criminal. Failure to adhere to committee rules during an investigation may thus have severe legal consequences.
Committees generally have adopted their own procedural rules for issuing subpoenas, taking testimony, and conducting depositions. Moreover, each committee may alter these rules at the commencement of each Congress. This Congress, a number of committees have enhanced the authority of their chairmen to exercise investigative authorities.
House and Senate committees adopted their rules for the 114th Congress earlier this year. We have examined these rules and updated our table of authorities, which is attached. The committees of the House have further empowered their committee chairmen and staff to issue subpoenas and take depositions. Several Senate committees also have modified their rules. Committee rules are subject to the rules of the full House or Senate.
Some items of note:
While several House committee chairmen can issue subpoenas unilaterally, in the Senate, only the Permanent Subcommittee on Investigations permits the Chairman to issue a subpoena without the consent of the Ranking Member. The Committees on Agriculture, Nutrition, and Forestry, Commerce, Science, and Transportation, Homeland Security and Governmental Affairs, Small Business and Entrepreneurship, and Veterans’ Affairs permit the chairman to issue a subpoena so long as the ranking member does not object within a specified time period. Furthermore, the Health, Education, Labor, and Pensions (HELP) Committee can delegate its subpoena authority to the chairman, his designees, or a subcommittee with only notice to the ranking member and any other members requesting notice.
In the House, five committees now have the ability to compel depositions through a subpoena. The Committee on Oversight and Government Reform continues to have that authority and now the Committees on Energy and Commerce, Financial Services, Science, Space, and Technology, and Ways and Means have been granted staff deposition authority. The Chairman of each committee is permitted to issue the subpoena after only consultation with the ranking member and three days’ notice prior to the deposition. The Committee on Education and the Workforce has roughly identical rules but specifically notes that it requires authorization from the full House to compel a witness to appear for a deposition.
Five Senate bodies have received Senate authorization to take depositions. The Senate Committee on Homeland Security and Governmental Affairs and its Permanent Subcommittee on Investigations receives authority each Congress from the Senate’s funding resolution. The Aging and Indian Affairs Committees were authorized by S. Res. 4 in 1977, which the committees incorporate into their rules each congress. The Ethics Committee’s deposition power was authorized by S. Res. 338 in 1964, which created the committee and is incorporated into its rules each Congress. And the Intelligence Committee was authorized to take depositions by S. Res. 400 in 1976, which it too incorporates into its rules each Congress.
Other Senate committees, namely the Committees on Agriculture, Commerce, Foreign Relations, and Small Business and Entrepreneurship authorize depositions in their rules. The Small Business and Entrepreneurship Committee went further this Congress and authorized staff to take those depositions at the Chairman’s discretion. However, it is not clear that such deposition authority is authorized by the Senate and, hence, it is similarly not clear whether appearance at a deposition can be compelled. The Senate’s view appears to be that Senate Rules do not authorize staff depositions pursuant to subpoena. Hence, Senate committees cannot delegate that authority to themselves through committee rules. It is thus understood that such authority can only be conferred upon a committee through a Senate resolution.
Our table provides a general sense of what rules apply in given circumstances. But it is essential to look carefully at a committee’s rules to understand specifically how its authorities apply in a particular context.
If you have any questions about how a committee’s rules apply in a given circumstance, please feel free to contact us for assistance.
Congressional investigations are unique exercises, and our table of committee authorities is meant to provide a sense of how individual committees can compel a witness to cooperate with its investigation. Gibson Dunn lawyers have extensive experience in both running congressional investigations and defending targets of and witnesses in such investigations. We are available to assist should a congressional committee seek information or documents from you.
