Mahmoud Khalil, a Columbia University graduate student and lawful permanent resident, filed a federal lawsuit in July 2026 alleging that Trump administration officials conspired with conservative organizations to target him for immigration detention based on his pro-Palestine advocacy. The lawsuit, filed in U.S. federal district court in Manhattan on July 14-15, 2026, names current and former Trump administration officials including Secretary of State Marco Rubio, Secretary of Homeland Security Markwayne Mullin, and acting Attorney General Todd Blanche, alongside the Heritage Foundation, a conservative think tank, and two pro-Israel surveillance groups: Betar and Canary Mission.
Khalil’s case illustrates a growing tension between free speech protections and immigration enforcement during the second Trump administration, with the plaintiff alleging that his detention was punishment for political speech rather than a legitimate immigration matter. Khalil was arrested by ICE agents on March 8, 2025, and held in immigration detention in Louisiana for 104 days—a period during which his first child was born without his presence. He contends that his arrest and detention were not based on immigration violations but rather retaliation for pro-Palestine activism and statements. The lawsuit invokes the Ku Klux Klan Act of 1871, a Reconstruction-era statute that restricts government coordination with private vigilante groups, arguing that federal officials worked in concert with conservative organizations to identify and target individuals for deportation based on their political views.

What Is Project Esther and How Did It Target Pro-Palestine Activists?
According to Khalil’s complaint, the Heritage Foundation created a blueprint called “Project Esther” designed to systematically dismantle the pro-Palestine movement in the United States. The strategy allegedly involved identifying prominent non-citizens who engaged in pro-Palestine advocacy and conflating legitimate political speech with anti-Jewish sentiment to justify their deportation. This approach would allow the government to remove immigrants who voiced criticism of Israeli policies while maintaining a façade of neutral immigration enforcement rather than political targeting.
The lawsuit alleges that Betar, a far-right Zionist youth movement, and Canary Mission, a pro-Israel surveillance organization, were instrumental in identifying targets for the conspiracy. Both groups maintained databases and online platforms documenting individuals who engaged in pro-Palestine activism, essentially creating lists that allegedly fed into the deportation pipeline. Canary Mission, in particular, had previously compiled dossiers on activists, making their role as an alleged partner in this scheme especially troubling from a civil liberties perspective—the organization operated without government oversight yet allegedly directly influenced federal immigration decisions.
The Legal Theory Behind the Ku Klux Klan Act Claim
The lawsuit’s central legal argument relies on the Ku Klux Klan Act of 1871, a statute enacted during Reconstruction to prevent state and local government officials from conspiring with private individuals or groups to violate citizens’ constitutional rights. While the law is nearly 150 years old, it remains applicable to modern scenarios where government officials coordinate with private entities to suppress constitutionally protected conduct. By framing Heritage Foundation officials, Betar members, and Canary Mission operators as the “vigilante” component of this conspiracy, Khalil’s attorneys argue that federal officials cannot lawfully work with them to target individuals based on political speech.
The challenge with this legal theory is that it requires proving both coordination and specific intent to violate constitutional rights, rather than simply disagreeing with enforcement priorities. The trump administration will likely argue that immigration enforcement decisions were made independently based on immigration law, not political viewpoint, and that any contact with Heritage Foundation members or pro-Israel groups was coincidental or part of normal policy consultation. However, if evidence emerges showing explicit discussions about targeting pro-Palestine advocates for deportation, or if communications reveal that enforcement decisions were made based on political speech rather than immigration status, the Klan Act argument gains substantial weight.
The Personal Impact of 104 Days in Immigration Detention
Khalil’s detention lasted 104 days in a Louisiana immigration facility—a duration that had profound personal consequences. He missed the birth of his first child, an experience that cannot be recovered and that his legal team argues demonstrates the severity of harm caused by the alleged conspiracy. During this period, he had limited access to legal counsel, faced uncertainty about his immigration status, and endured the psychological toll of detention in a facility far from his family and community support networks.
Immigration detention in the United States operates under different rules than criminal incarceration, with fewer due process protections and limited access to legal representation. Detainees often lack the ability to secure bail or release on their own recognizance, particularly non-citizens facing removal proceedings. The condition of Khalil’s detention—held in Louisiana while his life, family, and education were based in New York—exemplifies a common practice where immigrants are transferred far from their support systems to complicate legal defense and increase the pressure to accept deportation rather than fight their case through the legal system.
The Evidentiary Challenge of Proving Conspiracy
Winning a conspiracy case against government officials requires Khalil’s legal team to demonstrate explicit coordination and shared intent among disparate actors—Heritage Foundation members, Betar activists, Canary Mission operators, and Trump officials—across different organizations with different nominal purposes. This is substantially more difficult than proving that a single government actor made a biased decision. Unlike a straightforward civil rights claim alleging discriminatory enforcement, a conspiracy case requires evidence of communication, coordination, and agreement among multiple parties.
Khalil’s attorneys will need to rely on documentary evidence—emails, meeting notes, policy memoranda—showing that Heritage Foundation blueprint was shared with government officials, that Canary Mission data was directly used in immigration decisions, or that officials explicitly discussed targeting pro-Palestine activists. Without such evidence, the case becomes circumstantial, relying on timing, proximity, and pattern evidence to suggest coordination. This comparison highlights why conspiracy claims are rare in immigration cases: the government can often accomplish the same goal through facially neutral enforcement decisions without leaving the explicit paper trail that a conspiracy case requires.
Political Speech Protections in Immigration Enforcement
A critical limitation in Khalil’s case is that immigration enforcement is not typically subject to the same free speech protections that apply in criminal prosecutions. The First Amendment protects individuals from government punishment for political speech, but courts have traditionally given immigration authorities broad deference in making enforcement decisions. An official might theoretically be hostile to pro-Palestine activism while still making immigration decisions based on lawful grounds—visa overstays, unauthorized work, criminal history—that are separate from political viewpoint.
The warning here is essential: even if Khalil’s political speech contributed to his targeting, the government could argue that it simply accelerated enforcement that would have eventually occurred anyway based on immigration violations. If there were any technical defects in his immigration status or any grounds for removal other than his activism, the Trump administration could argue these provided an independent, non-retaliatory basis for deportation. This defense strategy—the so-called “independent contractor” defense—has historically insulated government officials from First Amendment retaliation claims where multiple potential justifications exist for the contested action.
The Role of Conservative Think Tanks in Immigration Policy
The Heritage Foundation, named as a defendant, is one of the most influential conservative think tanks in the country and has historically shaped Republican immigration policy since the 1980s. During previous Trump administrations and under other Republican presidents, Heritage Foundation staff members rotated into government positions, creating a revolving door between the organization’s policy development and actual government implementation.
The lawsuit suggests this institutional relationship went further—that Heritage Foundation personnel didn’t merely advise policy but actively participated in identifying specific individuals for enforcement action. Stephen Miller, named as a defendant and Trump’s chief immigration architect, has long-standing connections to conservative think tanks and immigration restrictionist circles. Miller’s role in crafting and implementing immigration policy during the first Trump administration is well-documented, but the allegation that he coordinated with outside groups to target individuals based on political speech, rather than immigration status, represents a more serious claim—one that implicates both his official duties and potential abuse of power.
Comparable Cases and Precedent
Khalil’s case is not the first allegation of politically motivated immigration enforcement, though most previous cases involved individual discrimination rather than alleged organizational conspiracy. In 2017, litigation emerged over ICE’s targeting of sanctuary city activists, with civil rights groups arguing that immigration enforcement was being weaponized against political opponents of Trump administration policies. Those cases settled or faced significant legal obstacles because proving coordinated intent across multiple government agencies proved difficult.
Another comparable framework involves cases against the FBI for alleged targeting of Muslim Americans after 9/11. Those litigation efforts faced similar evidentiary barriers: even when the FBI demonstrably focused resources on Muslim communities, courts struggled to distinguish between law enforcement prioritization based on security concerns versus religious discrimination. Khalil’s case carries similar structural challenges, though the addition of private-organization defendants (Heritage Foundation, Betar, Canary Mission) creates both new opportunities for discovery and new complications in proving coordination.
Immigration Status and Legal Residency During Trump’s Second Term
Mahmoud Khalil held lawful permanent resident status—a green card—making him technically a resident of the United States with significant constitutional protections, though not the fullest protections afforded to citizens. His status as a Columbia University graduate student, pursuing advanced education, also distinguishes his case from typical immigration enforcement scenarios. The lawsuit emphasizes that Khalil was not an undocumented immigrant or visa overstay, categories that typically generate less public sympathy and face different legal frameworks.
His detention despite lawful status raises sharper questions about whether immigration authorities were acting on legitimate grounds or applying enforcement selectively based on political criteria. The filing in Manhattan federal court in July 2026 places the case in the Southern District of New York, a venue that has historically entertained complex civil rights litigation and conspiracy claims against government officials. Khalil is represented by the Center for Constitutional Rights, a public interest law firm with extensive experience in government accountability cases. The specific allegations—coordination with Heritage Foundation, surveillance by Canary Mission, and targeting based on pro-Palestine advocacy—will require the court to examine whether immigration enforcement can be used as a tool for suppressing political speech, a question with implications extending far beyond Khalil’s individual case.
