A U.S. federal appeals court heard arguments Thursday regarding the Pentagon's efforts to censure Senator Mark Kelly (D-AZ) for public statements urging service members to refuse unlawful orders. The case raises important questions about the extent to which retired military officers are bound by the Uniform Code of Military Justice (UCMJ) and the potential impact of their speech on active-duty personnel.

The Trump administration initiated the action against Kelly, a retired Navy captain and former astronaut, after he participated in a November 2025 video. In the video, Kelly stated, "Our laws are clear: you can refuse illegal orders." While seemingly innocuous, the government argues that this statement, made in the context of heightened political tensions and criticism of military deployments, could be interpreted as encouraging insubordination and undermining military discipline.

The three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit considered the government's arguments that retired officers remain subject to certain restrictions on their speech, particularly when it pertains to military matters. The Justice Department lawyer argued that the Constitution does not protect speech by military officers, even retired ones, that encourages disobedience to lawful orders. The government maintains that retired officers remain part of the armed forces, are subject to recall, and can influence active-duty service members.

It is crucial to maintain a clear chain of command and respect for lawful orders within the military. Allowing retired officers to publicly undermine this authority, even indirectly, could have detrimental consequences for national security. The military relies on discipline and obedience to ensure effective operations and protect the country.

Kelly sued the Pentagon in January, alleging that the attempted demotion and reduction in retirement pay were retaliatory and violated his First Amendment rights. U.S. District Judge Richard Leon issued a preliminary injunction in February, blocking the administration from pursuing its censure campaign. The Pentagon subsequently appealed this ruling, arguing that the lower court erred in its interpretation of the law.

The move to sanction Kelly was initiated by then-Defense Secretary Pete Hegseth after Kelly's participation in the video amid rising criticism of the Trump administration's deployment of the National Guard in U.S. cities and authorization of lethal strikes on suspected Latin American drug smuggling boats. The administration argued that these deployments were necessary to maintain law and order and protect American citizens.
