It is being alleged that Attorney General Sessions gave untruthful testimony in his confirmation hearing. Specifically, in response to a question from Senator Franken about communications between Trump surrogates and representatives of the Russian government in the course of the 2016 presidential campaign, Sessions responded: “Senator Franken, I’m not aware of any of those activities. I have been called a surrogate at a time or two in that campaign and I did not have communications with the Russians, and I’m unable to comment on it.” In fact, Sessions apparently did have two discussions with the Russian ambassador during 2016, although it is unclear whether they discussed anything regarding the election.
For present purposes, we will skip the (serious) issue of whether there is a plausible basis for viewing this testimony as perjury or a material false statement that could be the basis of a criminal prosecution. Assuming that such a basis exists, there is an interesting legal question that arises. Would Sessions be immune from prosecution under the Speech or Debate Clause? For the reasons set forth below, the answer is probably no.
