Ohio National Guard members use encrypted Signal chat to question Trump's city deployments

NPR reported on November 10, 2025, that members of the Ohio National Guard were using an encrypted Signal group chat to express alarm about President Trump's domestic city deployments. The chat had formed in the months after Trump took office in January 2025 as Guard members tracked an escalating series of executive orders directing National Guard units to deploy inside American cities. Three Guard members, identified only by their first initials J, C, and A because they were not authorized to speak to the press and feared retribution, agreed to talk to NPR about what they were discussing in the chat.

The members described a shared sense of unease about the scope and vagueness of the orders. 'Is this really happening?' was the question members returned to repeatedly, according to NPR's November 13 follow-up. The chat itself functioned as an informal peer accountability structure in the absence of clear formal guidance from the chain of command about the legal basis and limits of their deployments.

The deployments that prompted the Signal chat began in the summer of 2025 when Trump sent National Guard troops into Los Angeles as anti-ICE protests escalated. The administration then deployed Guard troops into Washington, D.C., where approximately 2,300 Guard personnel were regularly patrolling streets by November 2025. About 150 of those were from the Ohio National Guard specifically. A further wave of deployment plans then arrived covering Chicago, Portland, Memphis, and cities in Louisiana and Missouri.

The Guard members told NPR the orders were 'unusually vague' compared to the clear, specific orders they had always received for prior domestic deployments like hurricane response or civil unrest support. One member said: 'What exactly are we going to be doing? Are we going to have leave? And those answers aren't very clear, but in the past, it's always been very clear.'

The critical legal question the Guard members were wrestling with involves the Posse Comitatus Act of 1878, which prohibits the use of federal military personnel to enforce domestic law. The Act creates a fundamental constraint on deploying the U.S. military as a domestic police force. However, National Guard members are typically not covered by Posse Comitatus when they operate under state authority and report to their governor, because the law applies only to federalized forces operating under Title 10.

The Trump administration sent the Ohio Guard members to D.C. under Title 32 orders, meaning they remained under state authority while receiving federal funding for a federal mission. This legal distinction matters enormously: Title 32 status allows Guard members to conduct law enforcement activities that Title 10 federalized forces cannot. But Guard members and civil liberties lawyers noted that the practical reality of patrolling American city streets alongside federal law enforcement still raised accountability questions that the Posse Comitatus framework was designed to address.

Federal courts began intervening in the domestic troop deployments earlier in 2025. U.S. District Judge Charles Breyer issued a September 2, 2025 ruling finding that the Trump administration's deployment of the National Guard in California violated the Posse Comitatus Act. In a 52-page opinion, Breyer found that the administration 'systematically used armed soldiers and military vehicles to set up protective perimeters and traffic blockades, engage in crowd control, and otherwise demonstrate a military presence in and around Los Angeles.'

Breyer's injunction blocked Trump and Defense Secretary Pete Hegseth from using troops in California for 'arrests, apprehensions, searches, seizures, security patrols, traffic control, crowd control, riot control, evidence collection, interrogation, or acting as informants.' The administration appealed. The California case established a judicial precedent directly relevant to the Ohio Guard members' concerns about what they were being asked to do in other cities.

The Supreme Court separately blocked the National Guard's deployment to Chicago under Title 10 authority in a ruling that restricted presidential power to federalize Guard units for domestic deployments. This ruling, combined with the Breyer California injunction, created a legal landscape in which the administration was pursuing deployments under Title 32 state-authority structures in part to avoid the Posse Comitatus restrictions that would apply to fully federalized forces.

The HSToday analysis noted that the administration's use of Title 32 status as a workaround for Posse Comitatus restrictions was itself contested. The Center for National Security and the Law (CNAS) published an analysis titled 'Preventing the Use of the National Guard to Evade the Posse Comitatus Act' arguing that the structural purpose of Posse Comitatus could be nullified if the Title 32 workaround was allowed to stand.

The White House did not dispute the existence of the Signal chat but defended the deployments. White House spokesperson Abigail Jackson said Trump was using his 'lawful authority to protect federal assets and personnel.' The administration's legal position rested on the president's commander-in-chief authority and on statutory provisions allowing deployment of the Guard for federal mission support under Title 32.

The Ohio Guard members told NPR they were not questioning the president's authority in the abstract but were asking whether the specific orders they were receiving crossed a line between lawful federal mission support and domestic law enforcement that would violate their oaths to the Constitution. 'What am I willing to do? What am I willing to give up?' was the question they said Guard members in the chat were openly asking each other, according to the NPR Consider This episode from November 13.

The broader deployment picture as of November 2025 involved approximately 2,387 Guard personnel mobilized in D.C., drawn from D.C., Louisiana, Mississippi, Ohio, South Carolina, West Virginia, Georgia, and Alabama, according to Task and Purpose reporting. The D.C. National Guard mission had been extended through February 2026 by CNN's October 2025 report. A 'Summer Surge' task force had outlines published by the National Guard Association of the United States describing expanded patrols.

The Ohio Guard members specifically described their D.C. deployment as 'so out of the scope of normal operations' that it prompted the creation of the Signal chat to work through the ethical and legal questions together. They said that in prior deployments for disasters or civil unrest under clear state authority with explicit mission parameters, they never felt the need for an unofficial accountability channel. The vagueness of the current orders made such informal channels feel necessary.

The Signal chat as a phenomenon speaks to a structural gap in military accountability. Service members have an individual duty to disobey unlawful orders under the Uniform Code of Military Justice, but they also face significant professional and personal risk for doing so. The Constitution Center's explainer on the National Guard controversy noted that the tension between following orders and upholding constitutional limits has no clean procedural resolution when the orders are technically authorized but ethically contested.

The Ohio Guard members' use of Signal specifically, an end-to-end encrypted application, for these conversations also raised questions about command awareness. If Guard members felt they could only have these conversations on an encrypted platform where their chain of command could not monitor them, it indicated a significant breakdown in the normal channels through which concerns about lawful orders are raised and addressed formally.
