Democratic Senator Mark Kelly filed a lawsuit against the Pentagon on Monday, alleging that the Trump administration violated his free speech rights by attempting to penalize him for speaking out against unlawful orders given to U.S. troops. Kelly, a former astronaut and U.S. navy pilot representing Arizona, is challenging the censure imposed on him by Defense Secretary Pete Hegseth. Hegseth’s censure, issued on January 5, is considered a formal step that could lead to a demotion from Kelly’s retired captain rank and a reduction in retirement benefits.
In response, Kelly petitioned the federal court in Washington, D.C., to declare the censure, rank proceedings, and any subsequent disciplinary actions against him as unconstitutional and unlawful. His lawsuit emphasizes that the government, under the First Amendment, is prohibited from punishing or retaliating against individuals for expressing protected speech, especially when it pertains to matters of public policy.
The case, now under the purview of U.S. District Judge Richard Leon, nominated by former President George W. Bush, marks a rare instance of a sitting senator taking legal action against the defense secretary. This move is part of a broader trend among lawmakers challenging what they perceive as overreach by the executive branch. The censure against Kelly originated from his involvement in a video alongside five other Democratic lawmakers in November 2025, where they urged troops to uphold the Constitution and resist unlawful commands.
Despite facing scrutiny, Kelly and his fellow lawmakers have stood by their video message, which coincided with the Pentagon’s actions against suspected drug-smuggling vessels near Venezuela. President Donald Trump, in a subsequent social media post, accused the legislators of sedition, a charge he suggested was punishable by death. Following the release of the video, the Pentagon initiated an investigation into Kelly, citing a federal law that enables retired service members to be called back to active duty for potential disciplinary actions.
Although all six lawmakers featured in the video have military or intelligence backgrounds, Kelly is the sole target of investigation due to his formal retirement status and continued jurisdiction under the Pentagon. The lawsuit lists Hegseth, the Defense Department, Navy Secretary John Phelan, and the Navy as defendants. Kelly affirmed his commitment to defending the rights of those who have fought to protect American freedoms, condemning Hegseth’s actions as an attempt to stifle dissent by threatening military veterans with rank and pay repercussions.
