The Department of Homeland Security is seeking neighborhood “rapid response” Signal group chats as it defends itself in a lawsuit accusing it of violating protesters’ First Amendment rights, according to recent court filings. Attorneys for protesters in the case argue that the move itself is a First Amendment violation. This included starting group chats on Signal to share when and where DHS operations were taking place. In June, attorneys for the protesters sent a letter to the Department of Justice, saying that they were intentionally withholding all community group Signal chats that would otherwise be considered responsive to the government’s requests. Attorneys for the government also deposed plaintiffs and tried asking them numerous questions about the community Signal group chats.
