Donald Trump, Jr., has claimed that the attorney-client privilege allows him to dummy up before a Congressional committee concerning a meeting with Daddy because there was an attorney in the room at the time. Quite apart from being laughable on its face, there appears to be a more fundamental problem that Junior faces with respect to his assertion of attorney-client privilege. It seems that the attorney-client privilege may not be a bar to a Congressional inquiry in the same way that it is in the context of a judicial proceeding. See The Attorney-Client Privilege in Congressional Investigations. That is, even if the communication was a legitimate attorney-client communication, Junior could still be compelled to testify.
