FBI Tip Claimed Mahmoud Khalil Called for “Violence on Behalf of Hamas” Two Days Before ICE Arrest

The FBI probe was promptly closed and found Khalil did not “warrant further investigation.” The Trump administration kept calling him a threat.

A recently released FBI file shines new light on the days immediately leading up to the arrest of then-Columbia University student and Palestinian rights activist Mahmoud Khalil.

On March 6 of last year, two days before unidentified officers from Immigration and Customs Enforcement abducted and arrested Khalil at his home, the FBI received an anonymous tip claiming that Khalil, listed incorrectly as a 22-year-old, had called for “violence on behalf of Hamas.” 

According to the heavily redacted documents, as of March 19, 2025, the FBI had closed an investigation into the tip and determined that Khalil “does not warrant further FBI investigation.” But by then, ICE had already secretly taken Khalil, now 31, thousands of miles away to a detention center in Louisiana. Despite the FBI’s decision to close the tip, the Trump administration continued to paint Khalil as a “Hamas supporter” and a threat to national security. 

It’s unclear if the FBI tip was directly related to Khalil’s ICE arrest, and the FBI did not respond to The Intercept’s question about whether the tip was shared with ICE. But Hamid Bendaas, a spokesperson at the Institute for Middle East Understanding, which has worked with Khalil since his arrest, said the timing reflects “a threat to us all.”

Though the FBI document says Khalil did not warrant further investigation, “that didn’t stop ICE from holding him in a detention center and separating him from his wife and newborn son for months,” Bendaas said. 

The document comes to light as the Trump administration has fast-tracked Khalil’s deportation case, which Khalil’s legal team argues is a form of retaliation against his protected political speech in support of Palestine. Khalil’s team received the FBI document, which has not been previously reported, via a lawsuit over a public records request and shared it exclusively with The Intercept.
