## Facts

- Senator Mike Gravel obtained a copy of the classified “Pentagon Papers,” a Defense Department study concerning U.S. decision-making in the Vietnam War.
- Gravel convened a Senate subcommittee meeting, read portions of the Papers into the record, and arranged for the full text to be inserted into the subcommittee record.
- Gravel also helped arrange for private publication of the Papers through Beacon Press.
- A federal grand jury investigating potential crimes related to acquisition and dissemination of classified materials subpoenaed Gravel’s aide, Leonard S. Rodberg, and certain third parties to testify.
- Gravel intervened and sought to quash the subpoenas, asserting that compelled testimony would violate the Speech or Debate Clause.
- The district court denied the motions to quash but entered a protective order limiting questioning; the court of appeals affirmed denial and modified the protective order, including recognizing protection for “legislative acts” and an additional common-law-type privilege for private publication.

## Issues

1. Whether the Speech or Debate Clause extends to a Senator’s aide to the same extent as to the Senator for legislative acts.
2. Whether the Speech or Debate Clause bars grand jury questioning about the acquisition of the Pentagon Papers.
3. Whether the Speech or Debate Clause or any other privilege bars grand jury questioning about arrangements for private publication of the Papers.

## Decision

- The Supreme Court held that the Speech or Debate Clause protects congressional aides as the Member’s “alter egos,” but only to the extent the aide’s conduct would be immune if performed by the Member as a legislative act.
- The Court held that arranging for private publication through Beacon Press was not a protected legislative act and could be the subject of grand jury questioning.
- The Court rejected any nonconstitutional testimonial privilege that would bar grand jury inquiry into private publication activities.
- The Court concluded the lower court’s protective order was too broad to the extent it foreclosed questioning beyond legislative acts; the grand jury could inquire into nonlegislative matters, including sources of the documents, so long as questioning did not implicate legislative acts.

## Legal Principles

- Speech or Debate Clause immunity is functional and confined to “legislative acts” integral to congressional deliberation and proceedings.
- The Clause’s protection extends to congressional aides when, and only when, their acts are within the same legislative sphere that would immunize the Member.
- The Clause does not protect all conduct related to a Member’s office and does not bar investigation of nonlegislative conduct merely because it is factually connected to legislative activity.
- Private republication through a nongovernmental press is not a legislative act and is not constitutionally immune from grand jury inquiry.
- Courts should prevent circumvention of the Clause by barring questioning into protected legislative acts, including preparatory and communicative steps that are part of the legislative process, while permitting inquiry into separable, nonlegislative matters.

## Conclusion

The Court affirmed robust Speech or Debate Clause protection for legislative acts by Members and their aides, but refused to extend that immunity to private publication efforts, allowing grand jury questioning into nonlegislative conduct such as publication arrangements and document sources when inquiry does not intrude on legislative acts.
