A green card holder and former Palestine solidarity activist sued the Trump administration in July 2026, alleging that senior federal officials coordinated with conservative and pro-Israel advocacy groups to target him for deportation based on his political speech. Mahmoud Khalil filed the 131-page lawsuit on July 14, 2026, in U.S. federal district court in Manhattan, naming Secretary of State Marco Rubio, White House Deputy Chief of Staff Stephen Miller, Acting Attorney General Todd Blanche, Secretary of Homeland Security Markwayne Mullin, and former DHS Secretary Kristi Noem as federal defendants. The lawsuit invokes an obscure Reconstruction-era statute—the Ku Klux Klan Act of 1871—originally designed to prevent government officials from working with vigilante groups to persecute citizens based on their political beliefs or activities.
Khalil’s case centers on his arrest on March 8, 2025, followed by 104 days in an immigration detention center in Louisiana. The lawsuit alleges that his detention was not a routine immigration enforcement action but rather a coordinated campaign orchestrated through what the Heritage Foundation calls “Project Esther”—an initiative designed to dismantle the pro-Palestine movement by conflating pro-Palestine advocacy with anti-Jewish sentiment. The private defendants named in the suit include the Heritage Foundation think tank, Betar (a far-right Zionist youth movement), and Canary Mission (a pro-Israel surveillance organization). If substantiated, the allegations suggest a blueprint for using federal immigration enforcement as a tool to suppress political speech through coordination between government agencies and private advocacy groups.

How Can Federal Officials Be Sued Under a 19th-Century Anti-KKK Law?
The Ku Klux Klan Act of 1871 was passed during Reconstruction to prevent local and state officials from conspiring with white supremacist militias to deprive Black Americans of their constitutional rights. Section 1985(3) of the statute permits private citizens to sue government officials who conspire to deprive them of constitutional rights through discriminatory action. Khalil’s lawyers argue that the law applies to modern circumstances in which government officials allegedly coordinate with private groups to suppress First Amendment rights, regardless of the specific cause championed by the targeted activist.
This legal theory requires proof of four elements: a conspiracy, an overt act in furtherance of that conspiracy, an injury to the plaintiff, and deprivation of a constitutional right. The lawsuit argues that Khalil’s arrest and detention violated his right to free speech and political association—constitutionally protected activities. Using a Reconstruction-era statute in 2026 to challenge alleged coordination between federal immigration enforcement and pro-Israel advocacy groups represents a significant legal stretch from the law’s original historical purpose, though the statute’s text does not limit its application to racial discrimination.
What Is the Alleged “Public-Private Conspiracy” at the Heart of the Lawsuit?
The lawsuit alleges that the named federal officials coordinated with the Heritage Foundation, Betar, and Canary Mission to identify, arrest, and detain khalil specifically because of his past activism for Palestinian rights at Columbia University. Rather than being a function of ordinary immigration enforcement based on immigration status or national security criteria, the detention allegedly resulted from a deliberate targeting strategy developed by conservative advocacy groups and executed by federal officials. Canary Mission operates as a surveillance organization that documents pro-Palestine activism on college campuses and publishes dossiers online.
Betar has a history of mobilizing against pro-Palestine organizing efforts. The Heritage Foundation, through its “Project Esther” initiative, reportedly aims to systematize the treatment of pro-Palestine activism as a hate crime or civil rights violation. The lawsuit alleges these groups used their databases and networks to identify targets like Khalil for immigration enforcement action, while federal officials provided the governmental authority to arrest and detain. This arrangement—where private groups identify targets and government agencies execute enforcement—fits the statutory definition of a conspiracy, according to Khalil’s legal team.
Who Is Mahmoud Khalil and What Led to His Detention?
Khalil holds a valid U.S. green card and has lived in the country for years while pursuing graduate studies and participating in student activism. His primary public activity centered on Palestinian rights advocacy during his time as a student activist at Columbia University, where he participated in demonstrations, organizing efforts, and speech-making on campus. He had no known criminal record and no prior immigration violations before his arrest on March 8, 2025.
The Immigration and Customs Enforcement (ICE) agency took Khalil into custody without advance warning and transferred him to an immigration detention facility in Louisiana, where he remained for 104 consecutive days. During this period, immigration authorities pursued his deportation. The lawsuit does not specify the technical immigration grounds cited for the detention or removal proceedings, but asserts that these grounds were pretextual—that the real reason for his arrest was his political speech and activism. For context, the vast majority of immigration detention cases involve individuals with criminal histories or flagged immigration status issues; detaining a green card holder for four months based on student activism represents an unusual enforcement action.
What Exactly Is the Heritage Foundation’s “Project Esther”?
According to the lawsuit, “Project Esther” is a Heritage Foundation initiative aimed at systematically dismantling the pro-Palestine movement by redefining pro-Palestine advocacy as a form of antisemitism or hate activity. The project operates on the premise that pro-Palestine speech and anti-Jewish prejudice are equivalent, and should be prosecuted as such through federal civil rights law, immigration enforcement, and other government mechanisms. The Heritage Foundation, a prominent conservative think tank with direct influence over Trump administration policy, had already published materials outlining this approach before Khalil’s arrest.
Project Esther thus represents not a hidden conspiracy but a publicly articulated strategy. The lawsuit alleges that the federal officials named in the suit implemented this strategy by using immigration law as an enforcement tool. This distinguishes Khalil’s case from routine immigration enforcement: the lawsuit argues that federal officials adopted and executed a private advocacy group’s political agenda, blurring the line between legitimate law enforcement and weaponized political persecution.
What Are the Legal Barriers to Proving This Conspiracy Claim?
Proving a conspiracy under the Ku Klux Klan Act requires demonstrating not just that the defendant groups held anti-Palestinian views or that Khalil was detained, but that specific federal officials coordinated with the private defendants with the intent to deprive him of constitutional rights. This requires evidence of communications, meetings, policy directives, or other concrete proof of agreement and coordination. Khalil’s lawsuit will need to overcome the federal government’s assertion that immigration enforcement decisions are made independently by career civil servants and immigration judges, not influenced by outside political groups.
Courts are typically reluctant to second-guess immigration enforcement decisions or to attribute motives to government officials based on coincidences of timing or ideological alignment. A defense argument will likely emphasize that ICE detains thousands of individuals each year through decentralized decision-making processes, and that Khalil’s detention could result from any number of factors unrelated to his activism. Additionally, if Khalil’s immigration status contained any technical irregularities—even minor ones—the government may argue that his detention was justified on immigration grounds alone, regardless of any alleged private coordination.
How Do Courts Typically Handle Political Persecution Claims in Immigration Cases?
Political persecution claims in immigration cases normally proceed through asylum law, where individuals can argue they face persecution based on political opinion. Khalil’s approach—using the Ku Klux Klan Act—takes an unusual path by suing the government officials themselves for conspiracy rather than seeking protection through standard immigration relief channels. This means the case will be litigated in federal district court as a civil rights claim, not through the immigration court system.
Federal courts have occasionally found that government officials conspired to deprive individuals of constitutional rights, but these cases typically involve clear documentary evidence of coordination or explicit statements of discriminatory intent. For example, cases involving targeted prosecution of religious or political groups have succeeded when prosecutors’ emails or testimony revealed deliberate, bias-driven decision-making. Khalil’s legal team will need to produce similar evidence—communications, policy documents, or testimony from witnesses—establishing that the named officials knowingly coordinated with Heritage Foundation, Betar, and Canary Mission to target him specifically because of his activism.
What Specific Allegations Does the Lawsuit Make About the Coordination?
The 131-page lawsuit lays out specific factual allegations about how the coordination allegedly worked. The document identifies Canary Mission’s surveillance database as the mechanism through which Khalil was identified; Heritage Foundation’s “Project Esther” as the strategic framework; and the named federal officials as the implementers who authorized and executed the arrest and detention. The lawsuit allegedly includes evidence of how pro-Israel advocacy groups had flagged Khalil’s activism before his arrest.
Khalil’s legal team claims to have documentary evidence supporting these allegations, though the full contents of the lawsuit remain the basis for the case. If the lawsuit’s allegations can be substantiated through discovery—the process of exchanging evidence before trial—it could establish a pattern of coordination between the Trump administration and pro-Israel advocacy organizations. The case will proceed through federal court in Manhattan, where the lawsuit was filed, and discovery could reveal communications, meeting records, or other evidence of intentional coordination between the federal defendants and the private advocacy groups. The outcome of this case could significantly affect how federal agencies coordinate with outside advocacy groups on enforcement decisions.
