Gravel v. United States
In 1971, Senator Mike Gravel received a copy of the Pentagon Papers: a set of classified documents concerning U.S. involvement in the Vietnam war. Gravel then introduced the study, in its entirety, into the record of a Senate Subcommittee meeting. Gravel also arranged for the private publication of the papers by the Beacon Press. A federal grand jury subpoenaed Leonard Rodberg, one of Gravel's aides, to testify about his role in the acquisition and publication of the papers.
Did the subpoena of Senator Gravel's aide violate the Speech and Debate Clause of Article I of the Constitution?
Yes. The Court held that because the work of aides was critical to the performance of legislative tasks and duties, they were nothing less than legislators' "alter egos" and thus immune from subpoenas by the Speech and Debate Clause. Aides were exempted from grand jury questioning so long as Senators invoked the privilege on their behalf. Moreover, the Court held that the protections of the Speech and Debate Clause did not extend beyond the legislative sphere, ruling that Senator Gravel's arrangements with the Beacon Press were not constitutionally protected.
