Why the Pentagon Threatened to Court-Martial Senator Mark Kelly

Last updated 6 days ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

The Pentagon said on November 24, 2025, that a misconduct review of Senator Mark Kelly could lead to his recall for court-martial proceedings. Kelly and five other Democratic lawmakers had said in a November 18 video that service members “can refuse illegal orders.” The government argued that his statements undermined military discipline and that his status as a retired Navy captain receiving military pay kept him subject to military authority.

The threat developed into a formal reprimand and a review of Kelly’s retired rank, which a federal judge preliminarily blocked on February 12, 2026. The February 12 order addressed the censure and retirement-grade proceedings, rather than deciding a court-martial prosecution. The dispute tested how far military discipline can reach into a retired officer’s civilian political speech.

What happened after the court-martial threat

On January 5, 2026, Defense Secretary Pete Hegseth issued a Secretarial Letter of Censure, formally reprimanding Kelly over his public statements about military operations and leadership. Hegseth directed the Navy secretary to recommend whether Kelly’s retired grade should be reduced and warned that further conduct of the kind described in the letter could bring criminal prosecution or additional administrative action. The threatened consequence was a lower retired grade, meaning a lower retirement rank and reduced retirement pay.

In Kelly v. Hegseth, on February 12, 2026, the United States District Court for the District of Columbia preliminarily barred enforcement of both the censure letter and the Navy’s notice that it was starting proceedings on Kelly’s retirement grade. The censure is not a conviction or a dishonorable discharge, and it did not by itself reduce Kelly’s rank or pension.

In a March 18, 2026 order, District Judge Richard J. Leon paused the district-court proceedings pending the government’s appeal and said the preliminary injunction remained in full effect. The United States Court of Appeals for the D.C. Circuit heard oral argument in Mark Kelly v. Pete Hegseth, appeal No. 26-5070, on May 7, 2026.

The court history described here runs through the May 7, 2026 argument; Kelly’s present appellate and military status is not established by those dated records. An oral argument is not an appellate judgment.

What Kelly and the other lawmakers said

On November 18, 2025, Kelly appeared in a video with five other Democratic lawmakers, saying that members of the armed forces “can refuse illegal orders.” The other participants were Senator Elissa Slotkin and Representatives Chris Deluzio, Maggie Goodlander, Chrissy Houlahan and Jason Crow, who identified backgrounds in the Central Intelligence Agency, Navy, intelligence work, Air Force and Army, respectively.

In his November 24, 2025 statement, Hegseth said the other five participants fell outside the Pentagon’s jurisdiction: one had served in the CIA and four were former military members who had not retired from the military.

President Donald Trump wrote on November 20, 2025 that “SEDITIOUS BEHAVIOR” was “punishable by DEATH!” and reposted a call for the lawmakers’ hanging, according to the statements reproduced in Kelly’s complaint. Kelly and his colleagues responded jointly that their oath to the Constitution lasted a lifetime and criticized treating a restatement of the law as punishable by death.

Kelly’s complaint also reproduced Trump’s November 23, 2025 reposts accusing the six lawmakers of sedition and treason.

Kelly’s January 12, 2026 complaint described a U.S. campaign of strikes on boats allegedly smuggling drugs in the Caribbean Sea and Pacific Ocean, beginning in September 2025. The complaint cited reports that a September 2, 2025 second strike killed two survivors of a targeted boat; it treated those reports as allegations that prompted debate about the laws of war.

The Pentagon’s November 24, 2025 announcement said it had begun a misconduct review that might lead to recall for court-martial proceedings or administrative measures. Beyond the video, Kelly demanded an investigation of what Judge Leon’s later opinion calls “the boat strikes,” and in a November 30 CNN interview, asked whether a second strike to eliminate any survivors would be a war crime, he answered “it seems to” and said he would have refused to carry out such an order.

In the later censure, Hegseth accused Kelly of a pattern of public statements between June and December 2025 that characterized lawful military operations as illegal and counseled service members to refuse orders related to them, which he said undermined the chain of command. Hegseth’s letter formally accused Kelly of conduct prejudicial to good order and discipline and conduct unbecoming an officer, and described the censure as an administrative action. In plain English, those accusations concern harm to military discipline and behavior considered unfit for an officer. The reprimand stated Hegseth’s conclusions; it did not establish a criminal charge or a proven violation of military law.

Why military retirement matters

Article 2 of the Uniform Code of Military Justice (UCMJ), the military’s criminal-law system, includes retired members of a regular armed-forces component who are entitled to pay. A regular component is the standing part of a service; reserve components provide trained units and personnel for active duty when more are needed than the regular components have.

The government’s court filing described Kelly as a retired Navy captain who still received military pay and benefits, retained his rank and remained subject to recall. Hegseth made the same point when he reposted the Pentagon’s announcement, writing that Kelly “is still subject to UCMJ.” That continuing tie was the government’s basis for asserting authority over Kelly; its argument distinguished military retirement from simply having served and left.

A separate law, 10 U.S.C. § 688, lets the secretary of a military department order covered retirees back to active duty, under regulations set by the defense secretary and within the statute’s limits and exclusions.

Recall would raise a separate question: whether a senator can also hold a military office. The Constitution’s Incompatibility Clause bars a person holding an office under the United States from serving in either house of Congress while continuing in that office. The Senate itself has the constitutional power to expel a member, requiring a two-thirds vote. Neither rule means that a threat of recall automatically removes a senator from office.

Lawful orders, sedition and treason

Article 92 punishes failures to obey lawful orders or regulations and dereliction of duty, while Article 90 addresses willful disobedience of a superior commissioned officer’s lawful command. The word lawful is part of the legal requirement, not an exception invented by the lawmakers.

The Manual for Courts-Martial says an order to perform a military duty may be inferred to be lawful, and a subordinate disobeys it at his or her own peril. That inference does not apply to a patently illegal order, such as one directing a crime. The Manual treats an order’s lawfulness as a legal question for the military judge. These rules distinguish an unlawful command from one someone merely dislikes.

Article 94 defines mutiny through an intent to override lawful military authority, combined with concerted refusal of orders or duty, or violence or disturbance. Its sedition provision requires an intent to overthrow or destroy lawful civil authority and concerted revolt, violence or another disturbance against that authority. A political label is therefore no substitute for proving the specified intent and conduct. Hegseth called the recording a “sedition video”; Kelly and his colleagues said they had restated the law, and the judge who blocked the censure treated the statements at issue as protected speech.

Treason is a separate crime with a different constitutional definition: levying war against the United States, or adhering to its enemies by giving them aid and comfort. The Constitution permits a treason conviction only with two witnesses to the same overt act or a confession in open court. Criticism of an administration and constitutional treason are not equivalent descriptions.

For offenses covered by Article 94, the statute authorizes death or another punishment directed by a court-martial. The federal treason statute provides death or imprisonment of at least five years with a fine of at least $10,000, plus inability to hold an office under the United States. These are consequences the statutes attach to guilt, not a sentence imposed on Kelly or a forecast of his outcome.

Article 88 separately prohibits commissioned officers from using contemptuous words against specified officials and institutions, including the president and defense secretary. The Manual says emphatic criticism during a political discussion may not be charged under that article if it is not personally contemptuous. That article does not make every sharp criticism by a retired officer a military offense, and Hegseth’s censure rested on the conduct accusations described earlier.

The fight over rank, pay and political speech

Kelly’s lawyers warned Navy Secretary John Phelan in a December 15, 2025 letter that they would take appropriate legal action if the administration pursued proceedings they regarded as unconstitutional overreach.

Kelly’s January 12, 2026 complaint alleged that the Pentagon was punishing protected speech in violation of the First Amendment. He argued that censure and threatened rank or pay reductions would chill legislative oversight and warn other retirees against criticizing executive military policy.

The government answered that retirees remain part of the military community, receiving pay and benefits while retaining obligations to the service. In its January 22, 2026 filing, it argued that Kelly’s speech rights in military disciplinary matters were more limited than a private citizen’s and that the censure and review had not themselves changed his rank, pay or benefits. Under that argument, the review was an exercise of continuing military responsibility that civilian courts should not interrupt prematurely.

Retired Air Force Col. Rob Maness, who described himself as GatorPAC’s chairman and a conservative political advocate, supported Hegseth’s action in a January 12, 2026 post. He argued that retirees receiving military pensions remained accountable for conduct harmful to military discipline and that Kelly’s position in Congress amplified the damage he attributed to the video.

The retirement-grade statute ordinarily uses the highest permanent grade in which an officer served satisfactorily on active duty. Kelly argued that his satisfactory active service was complete and that the statute did not authorize reopening his retirement grade over later political speech.

Leon’s February 12, 2026 opinion agreed with Kelly that the government had not supplied precedent extending active-duty speech restrictions to military retirees, and treated the statements at issue as protected speech on public concerns. The judge found the required likelihood of success on Kelly’s First Amendment claim and reserved judgment on his other claims. The preliminary injunction stopped the challenged actions while the litigation proceeded; it did not settle every limit on retiree jurisdiction or every constitutional theory in the suit.

In an April 23, 2026 statement from National Security Leaders for America, which filed a friend-of-the-court brief in Kelly v. Hegseth, retired Navy Rear Admiral Michael Smith, the group’s founder and president, warned that threatening rank or pension over protected speech would cause other retirees to self-censor and leave public debate.

Being a member of Congress does not automatically bring every public statement under the Constitution’s Speech or Debate Clause, which protects lawmakers’ legislative work. In Hutchinson v. Proxmire, the Supreme Court said voting and committee reports are protected but press releases and newsletters are not. A public statement outside Speech or Debate protection can still raise a free-speech question.

What would change the answer

The 2025 threat raised two distinct questions: the military’s authority over a retiree and the constitutional protection for a lawmaker’s political speech. The February 2026 injunction answered a preliminary request for protection, without deciding every claim in Kelly’s suit.

The March 18 district order required a joint report on next steps within five days after the appeals court issued its mandate. The mandate, normally a certified copy of the appeals court’s judgment and any opinion, takes effect when issued under Federal Rule of Appellate Procedure 41.
