In Star Wars, the Imperial March is the music that plays when Darth Vader and his storm troopers enter the scene. It’s also the soundtrack of Sam O’Hara’s protest against the National Guard’s presence in D.C. National Guard troops arrived in the District after President Donald Trump deployed them to support local police—an act that Mr. O’Hara views as a violation of centuries-old norms against militarizing domestic law enforcement and a threat to individual freedom. To highlight the surreal danger of the deployment, Mr. O’Hara began walking behind Guard members when he saw them in the community, playing The Imperial March on his phone, and recording. Most community members got the point of the protest, and so did several members of the Guard, who either smiled or laughed in response. Ohio National Guard Sgt. Devon Beck, however, was not amused by the satire. He threatened to call MPD if Mr. O’Hara didn’t stop his protest. When Mr. O’Hara persisted, Sgt. Beck recruited MPD officers to the scene, and the officers proceeded to detain and handcuff Mr. O’Hara, ending his demonstration. The First and Fourth Amendments (not to mention D.C. law) bar government officials from detaining people just because of their speech. Mr. O’Hara is suing to vindicate that principle. Sgt. Beck moved to dismiss the claims against him, arguing among other things that he is entitled to the defense of qualified immunity because he did not violate rights that were "clearly established." That motion remains pending. Meanwhile, in June 2026, the remaining defendants — the D.C. government and its officers — agreed to compensate Mr. O'Hara in exchange for dismissal of the claims against them. Press Release

On September 25, 2025, four Washington, D.C. community members and the national immigration organization CASA sued the Trump administration to end its policy and practice of making immigration arrests in D.C. without a warrant and without probable cause. The plaintiffs are represented by the American Civil Liberties Union of the District of Columbia, American Civil Liberties Union, Amica Center for Immigrants’ Rights, CASA, National Immigration Project, the Washington Lawyers’ Committee for Civil Rights and Urban Affairs, and the law firm of Covington & Burling. Since August, federal officers from multiple agencies have made hundreds of immigration arrests in the District. The officers frequently patrol and set up checkpoints in neighborhoods where a large number of immigrants live and stop and arrest people as they go about their daily lives. The law typically requires an agent to have a warrant when arresting someone for an immigration violation. One exception to the warrant requirement is when the agent has probable cause both that a person is in the United States in violation of the law and is likely to escape before a warrant can be obtained. According to the lawsuit, the Trump administration has a policy and practice of making immigration arrests without a warrant and without an individualized determination of probable cause that the person is in the country unlawfully and that the person is a flight risk. Each plaintiff in the case was arrested, detained, and released. The lawsuit was filed as a class action. The plaintiffs seek a court ruling to prevent the government from conducting such unlawful arrests against them and others in the future. On October 3, 2025, Plaintiffs filed a motion for class certification and a motion for a preliminary injunction, to stay agency action, and for provisional class certification to ask the Court to order Defendants and their agents to stop making warrantless immigration arrests without probable cause for flight risk, as required by the Immigration and Nationality Act. On November 19, 2025, the district court heard oral argument on Plaintiffs’ motions. On December 2, 2025, the district court denied without prejudice Plaintiffs’ motion for class certification and granted in part and denied in part Plaintiffs’ motion for a preliminary injunction, to stay agency action, and for provisional class certification. It issued an order preliminarily enjoining the government from enforcing its policy or practice of making warrantless civil immigration arrests in D.C. without a pre-arrest individualized determination by the arresting agent of probable cause that the person being arrested is likely to escape before a warrant can be obtained. It also provisionally certified a class consisting of “[a]ll persons who, since August 11, 2025, have been or will be arrested in this District for alleged immigration violations without a warrant and without a pre-arrest, individualized assessment of probable cause that the person poses an escape risk” for purposes of the preliminary injunction. The court further ordered the government to document the facts supporting an arresting agent’s probable cause to believe a person is likely to escape before a warrant can be obtained and to periodically provide such documentation to Plaintiffs’ counsel. On February 19, 2025, Plaintiffs filed a motion to enforce the preliminary injunction, arguing that Defendants are not complying with the preliminary injunction based on the arrest records they produced for warrantless civil immigration arrests in D.C. after the district court’s December 2 order as well as recent public statements made by high-ranking DHS officials on the legal standard for arrests and an internal ICE memorandum that was issued on January 28. The relief Plaintiffs seek includes training for Defendants’ agents on the correct legal standard to apply when making warrantless civil immigration arrests and additional reporting requirements regarding warrantless civil immigration arrests in D.C. The district court has set argument on the motion for March 11 at 10:00AM. Following the hearing on March 11, both parties submitted supplemental briefing focused on the January 28th ICE memorandum, arguing that the memo misinterprets the probable cause standard for escape risk and asking the court to order Defendants not to rely on the probable cause standard or analysis in the memo. On May 7, 2026, the district court granted Plaintiffs' motion and ordered that “when conducting civil immigration arrests without a warrant in this District, defendants shall not rely on the probable cause standard or analytical approach set forth in the five-page memorandum from former Acting Director of Immigration and Customs Enforcement, Todd Lyons[.]”

Federal employees filed a complaint against the Trump administration for targeting workers, especially people of color, women, and non-binary workers, for participating in diversity, equity, and inclusion (DEI) activities, violating their First Amendment rights.
