via SayNothing.info. July 31:
On the advice of counsel, I invoke my right to remain silent under the Fifth Amendment to the United States Constitution. I am concerned that this grand jury is seeking information designed to infringe or chill my associational privacy, and that of others, guaranteed by the First Amendment to the United States Constitution, and that it is using information obtained without a search warrant in violation of the Fourth Amendment to the United States Constitution. I define the preceding statement as “invoke”, and when I say “I invoke” in the future I am referring to this statement.
From a grand jury session, as transcribed by David House.
