Brennan’s testimony Tuesday came as the Senate Intelligence Committee issued subpoenas for documents from two of former National Security Adviser Michael Flynn’s businesses. This is committee vice chair Mark Warner.

Sen. Mark Warner: “The other two were that we issued two subpoenas to the two Michael Flynn businesses that we’re aware of—Flynn Intel LLC and, I think, Flynn Intel, Inc.—both located in Alexandria, Virginia, with a specific list of documents, because while we disagree with General Flynn’s lawyer’s interpretation of taking the Fifth, clearer—it is even more clear that a business does not have a right to take a Fifth if it’s a corporation.”

Flynn himself has pleaded the Fifth and refused to comply with a Senate Intelligence Committee subpoena demanding he turn over documents related to his meetings with Russian officials.
