Senator Mark Kelly’s Pentagon lawsuit, filed January 12, 2026, challenges Defense Secretary Pete Hegseth’s move to censure the Arizona Democrat, strip him of his retired Navy rank, and reduce his pension after Kelly appeared in a video telling active-duty troops they can refuse unlawful orders. A federal judge blocked the punishment in February 2026, calling it a violation of Kelly’s First Amendment rights. The government has appealed, and the case is pending before the U.S. Court of Appeals for the D.C. Circuit.1CourtListener. Kelly v. Hegseth, Docket No. 1:26-cv-000812NPR.

The Video That Started It
On November 18, 2025, Kelly and five other Democratic lawmakers with military or intelligence backgrounds released a video addressed to service members and intelligence professionals. Senator Elissa Slotkin of Michigan and Representatives Jason Crow, Chris Deluzio, Maggie Goodlander, and Chrissy Houlahan joined him. The video went out during U.S. military strikes in the Caribbean and eastern Pacific and the deployment of National Guard troops to several American cities. The lawmakers said the administration was “pitting our uniformed military and intelligence community professionals against American citizens” and reminded troops that “our laws are clear. You can refuse illegal orders. You must refuse illegal orders.”3NBC News. Judge Blocks Mark Kelly Demotion Over Illegal Orders
President Donald Trump posted on Truth Social that the video was “SEDITIOUS BEHAVIOR AT THE HIGHEST LEVEL” and suggested it was “punishable by DEATH.”4Courthouse News Service.

What the Pentagon Tried to Do
On January 5, 2026, Hegseth issued a formal letter of censure accusing Kelly of “reckless misconduct” and alleging he “clearly intended to undermine good order and military discipline.”6The Daily Record. Judge Blocks Pentagon From Reducing Mark Kelly Rank and Pension The censure was a procedural step toward “retirement grade determination proceedings” under 10 U.S.C. § 1370, which lets the Defense Secretary reassess a retired officer’s rank for cause. If the proceeding succeeded, Kelly would have been demoted from his retired rank of Navy captain and had his pension reduced.4Courthouse News Service.

The Pentagon also signaled it could recall Kelly to active duty and court-martial him, invoking 18 U.S.C. § 2387, which criminalizes interfering with the loyalty, morale, or discipline of the armed forces.7The Guardian.

The Complaint
Kelly filed a 46-page complaint in the U.S. District Court for the District of Columbia on January 12, 2026, docketed as Case No. 1:26-cv-00081. He named Hegseth, the Department of Defense, Navy Secretary John Phelan, and the U.S. Navy as defendants.1CourtListener. Kelly v. Hegseth, Docket No. 1:26-cv-00081 The suit argues the censure and threatened demotion violated the First Amendment, the Constitution’s Speech or Debate Clause, and the separation of powers. Kelly’s lawyers described the Pentagon’s actions as the “first-ever example of military sanctions against a member of Congress for political speech.”4Courthouse News Service.

Eight days after the filing, 41 retired generals, admirals, and former service secretaries filed an amicus brief backing Kelly. The signatories had served under every president from Eisenhower through Trump. They argued that punishing a retired officer for restating settled law on unlawful orders would chill veterans’ participation in public life, and they described the duty to disobey unlawful orders as a “settled principle of military administration and federal law.”9States United Democracy Center.

Judge Leon’s Ruling
On February 12, 2026, Senior U.S. District Judge Richard Leon issued a 29-page ruling granting Kelly a preliminary injunction. The order stopped the Pentagon from carrying out any disciplinary action, the retirement-grade review, or any pension reduction while the case proceeded.2NPR. Mark Kelly Pete Hegseth Lawsuit Leon wrote that the Pentagon had “trampled on Senator Kelly’s First Amendment freedoms” and that the speech at issue was “unquestionably protected.”11CNN. Mark Kelly Pentagon Lawsuit Ruling He added that “punishing a sitting U.S. Senator for his views on military policy” was not routine business and called retired veterans contributing to public debate on military matters a “valuable asset for our country.”6The Daily Record.

Government lawyers argued Kelly was using his military status “as a sword and his legislative position as a shield.” Leon rejected the argument in a single word: “Horsefeathers!”8ABC 7 Chicago. Judge Temporarily Blocks Pentagon From Punishing Sen. Mark Kelly
The Appeal
Hegseth said the ruling would be “immediately appealed.”2NPR. Mark Kelly Pete Hegseth Lawsuit The case went to the U.S. Court of Appeals for the D.C. Circuit under an expedited schedule, docketed as No. 26-5070. A group of 73 amici filed a brief supporting the injunction on April 17, 2026.12States United Democracy Center. Kelly v.

The Parallel Criminal Track
The Pentagon proceeding was not the only front. The Justice Department pursued a separate line against all six lawmakers who appeared in the video. Beginning in November 2025, the FBI’s counterterrorism division sought interviews with each of them; none agreed. By early 2026, at least five had been contacted by federal prosecutors working under U.S. Attorney for the District of Columbia Jeanine Pirro.14The New York Times.

Prosecutors asked a federal grand jury in Washington, D.C., to indict the six on seditious conspiracy charges. On February 10, 2026, the grand jury declined and returned no indictment against any of them. Slotkin said the jurors “upheld the rule of law and determined this case should not proceed.” Kelly called the attempted prosecution an “outrageous abuse of power.”16CNBC.

What Is at Stake
Kelly retired from the Navy as a captain after a career that included service as a NASA astronaut, and his retired status is what gave the Pentagon a legal hook the department could not use against the other five lawmakers. The lawsuit tests whether the Defense Secretary can use the retirement-grade review process under § 1370 to punish a retired officer who is also a sitting senator for speech about military policy. Judge Leon’s ruling says no, at least at the preliminary stage. The D.C. Circuit’s decision on appeal will determine whether that answer holds and, more broadly, where the line falls between military discipline over retired officers and the constitutional protection of political speech by members of Congress.
