National security has become one of the most elastic rationales in the second Trump administration. Mother Jones reporter Sophie Hurwitz catalogued much of that range in a September 2026 report, including proposed tariffs on brass instruments, the push for Greenland, offshore wind restrictions, federal labor policy and the government’s intervention in litigation involving xAI.
The pattern matters because these are not variations on a single policy problem. They involve trade, territorial ambitions, labor relations, protest policing, environmental regulation and artificial intelligence. What connects them is the claim that ordinary limits should give way when national security is invoked.
The clearest example for federal workers came on March 27, 2025. Executive Order 14251 declared that a long list of agencies and agency subdivisions had as a primary function “intelligence, counterintelligence, investigative, or national security work” and said federal collective-bargaining law could not be applied to them consistently with national-security requirements.
AFSCME reported that the order ended collective-bargaining rights for about 950,000 employees collectively represented by six unions. The order covered organizations far beyond the intelligence community, including the Department of Veterans Affairs, the Environmental Protection Agency, the Food Safety and Inspection Service and most of the Treasury Department.

The order did not individually reclassify the jobs of those workers. Instead, it used a statutory national-security exclusion at the agency and subdivision level. That distinction matters because it explains how employees performing ordinary civilian functions could lose collective-bargaining protections without their day-to-day duties becoming intelligence or defense work.
Domestic-security policy followed a related path later that year. On September 22, 2025, Trump issued a separate order designating Antifa as a domestic terrorist organization. Three days later, National Security Presidential Memorandum-7 referred back to that order and directed Joint Terrorism Task Forces to coordinate investigations into political violence and related activity.
The distinction is more than clerical. The original draft attributed the designation itself to NSPM-7, but the White House documents show that the designation came first and the broader investigative memorandum followed.
Foreign policy supplies another example. Trump repeatedly framed control of Greenland as a national-security issue, and in July 2026 he revived the demand at the NATO summit. The Guardian reported that he again argued the United States should control the autonomous Danish territory even as European allies rejected the idea.

Environmental policy has produced a similar fight. The Associated Press reported that Interior Secretary Doug Burgum relied on a classified report from Defense Secretary Pete Hegseth in arguing that offshore wind projects posed national-security risks. Federal judges reviewed the government’s classified material and allowed all five halted offshore wind projects to resume construction.
The dispute illustrates an important limit on the national-security label: courts do not always accept it at face value. In the offshore-wind litigation, judges still examined whether the government’s stated rationale justified the action being taken.
The xAI dispute pushes the same argument into a different corner of domestic law. The Washington Post reported that the Justice Department sought to stop litigation over a power plant in Southaven, Mississippi, that supports xAI’s Colossus 2 data center just across the state line in Memphis.
The NAACP and environmental groups alleged that the turbines violated the Clean Air Act. The government argued that xAI’s models were important to national security because versions of Grok were being used in classified military operations, turning an environmental-enforcement dispute involving a privately owned AI system into a national-security case.
That does not mean every national-security argument is automatically illegitimate. Wind turbines can interfere with radar, AI systems can have military applications, governments have genuine security interests in critical technology, and presidents have long received substantial discretion in foreign affairs and defense.
The question is what happens when the category keeps expanding. A legal concept designed to give the executive flexibility around extraordinary threats becomes more consequential when it is used in labor relations, trade, environmental permitting, domestic investigations and disputes involving private companies.
That is the through-line connecting these otherwise very different stories. The important change is not that the words “national security” suddenly appeared in American government. They have been embedded in executive power for decades. What has changed is the range of ordinary policy fights into which those words are now being carried.
Federal employees will still process veterans’ benefits and administer government programs. Musicians will still need instruments. Energy developers will still apply for permits, and technology companies will still face environmental rules. The practical question is how often attaching a national-security rationale allows the executive branch to alter the rules governing all of them.
