O’Hara v. Beck – Defending the Right To Protest the National Guard

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. Press Release

Associated Press v. Budowich - Opposing Government Retaliation Against News Outlet for Refusing To Parrot White House's Views

In January 2025, President Donald Trump signed an executive order aiming to rename the Gulf of Mexico “Gulf of America.” When the Associated Press chose not to use the new moniker, the White House retaliated by barring the AP’s reporters from participating in the press pool in the Oval Office or aboard Air Force One. The news organization filed suit in February for retaliation in violation of its First Amendment rights, and it won a preliminary injunction in April. The government appealed. Together with the National ACLU, we filed an amicus brief at the D.C. Circuit supporting the AP and arguing that, although the disagreement about geographic nomenclature that began this controversy is a small one, the constitutional implications of the dispute itself are profound. American history shows that scrupulous protection of the press’s right to disseminate information, without fear or favor to those in power, is essential to our democracy. From early American history, to World War I, to the Second Red Scare, dark chapters in our Nation’s past illustrate what happens when we stray from our commitment to First Amendment freedoms. The White House’s exclusion of the AP is, alarmingly, part of a broader assault on free expression. Our brief catalogues how the administration has attempted to muzzle institutions like the bar, the academy, and the media that are at the heart of civil society. Constant vigilance for our liberties is as critical as ever. Finally, we explain how developments in other democracies and former democracies highlight the dangers of allowing the government to infringe speech and press freedoms. Across the world—including in the Philippines, Hungary, Turkey, and Russia—democracies have backslid into repressive regimes with few freedoms after their institutions failed to hold the line on free expression. Backsliding often begins with a crackdown on speech and the press. Our brief warns that condoning government retaliation against disfavored media outlets would not only fly in the face of First Amendment jurisprudence, but also ignore the warnings from our Nation’s history and from recent history around the world: that incursions on free expression, left unchecked, lead to increasing repression.

Arab Student Union of Jackson-Reed High School v. District of Columbia - Challenging suppression of pro-Palestinian student speech

The Supreme Court has long recognized that public school students do not “shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.” The District of Columbia recognized the same when it promulgated the D.C. Student Bill of Rights, which provides that “[e]ach student shall have the right to exercise his or her constitutional rights of free speech, assembly, and expression without prior restraint, so long as the exercise of these rights does not substantially interfere with the rights of others.” Yet Jackson-Reed High School refuses to allow the exercise of these rights by its Arab Student Union. The Arab Student Union is a recognized student club at Jackson-Reed High School, a public high school in the District of Columbia that is one of the most diverse high schools in the country. For the past four months, the club and its members have been trying to engage in expressive activities at the school—showing a documentary film, putting up posters, distributing literature, presenting a cultural program—but have been stopped at every turn by the school administration. Specifically, the school has denied the club permission to hold voluntary lunchtime meetings to screen a film critical of the Israeli government, and the school has refused even to consider alternative films proposed by the club. The school has censored handouts the club sought to distribute and prohibited them from distributing certain materials entirely. And the school has prevented them from holding a cultural event and then heavily curtailed what they could say at such an event. The Arab Student Union’s activities would not be disruptive; they are the same kinds of activities in which other student clubs engage. Their speech has been suppressed because the school does not want their viewpoint—which concerns the ongoing war in Gaza and its effects on the Palestinian people—to be heard. Representing the club, we sued D.C. and the principal of the school for violating the Arab Student Union’s (and its members’) First Amendment rights and their rights under the federal Equal Access Act and the D.C. Student Bill of Rights. We seek a court order that the students be allowed to show their film before the end of the school year and more generally to be permitted to express their views with their fellow students like any other student club at the school. A hearing on our motion for a preliminary injunction was scheduled for May 10, 2024. But on May 7, with the court’s strong encouragement, we began conversations with the defendants to see if we could reach an agreement about what the Arab Student Union could do during the remaining weeks of the spring semester. We eventually reached an agreement that allows the club to show one of the movies it had requested and to distribute its printed material, including one of the pages that had been censored. Principal Brown also agreed to send an email to all faculty and administrators reiterating that the standards for expressive activities apply equally to all student groups. The lawsuit will continue, so that we can clearly establish the right of the ASU and all student groups to exercise their First Amendment rights in D.C. Public Schools.

In 2015, police officers shot tear gas at two legal observers with bright green "Legal Observer" hats. The court ruled that words printed on clothing are not entitled to First Amendment protections. Together with the National ACLU and the ACLU of Missouri, we petitioned SCOTUS to review the case.
