Federal immigration authorities have detained Marwan Marouf, a longtime official with the Muslim American Society in Dallas, marking what analysts describe as a rare but significant strike against the Muslim Brotherhood’s network in Texas.
According to U.S. Department of Homeland Security records, Marouf first entered the country more than 30 years ago as an international student. He later married, raised a family in North Texas, and pursued permanent residency through his employer. His green card applications, however, repeatedly stalled under federal scrutiny over his organizational affiliations. On the morning of his detention, U.S. Citizenship and Immigration Services formally denied his petition, echoing concerns raised over a decade earlier.
Marouf is also tied by marriage to the Elashi family, central figures in two of the most consequential terrorism-financing prosecutions in U.S. history: the Infocom case of 2004–2005 and the Holy Land Foundation trial of 2008. In those prosecutions, Elashi family members were convicted of conspiring with Hamas political bureau chief Mousa Abu Marzook and funneling $12.4 million to Hamas under the guise of charity. The Holy Land Foundation case remains the largest terrorism-financing trial ever brought in the United States.
In response to Marouf’s detention, the Muslim Legal Fund of America quickly mobilized a defense campaign. In a press release, MLFA described Marouf as a “peaceful leader” who has “devoted significant efforts to a broad range of charitable causes.” The group cited his volunteer work with the Red Cross, disaster relief, Boy Scouts, and youth drug prevention programs. MLFA criticized federal officials for recycling “opinions from over a decade ago” to deny his green card application and accused the government of targeting Muslims unfairly.
Prominent Texas imam Omar Suleiman, founder of the Yaqeen Institute, also defended Marouf, calling him “the heart of our community” and urging supporters to rally. His public involvement underscores the close ties between MAS Dallas and Texas’s broader Islamic leadership.
Federal officials, however, maintain that Marouf’s organizational connections and family ties to Hamas’s U.S. support structure warrant scrutiny. Analysts argue the case reflects renewed federal willingness to confront entrenched Brotherhood-linked networks in the United States after years of limited enforcement.
The case now moves forward in immigration and federal court, where Marouf’s attorneys will argue for lawful permanent residency even as federal authorities emphasize his links to one of the most infamous terror-financing families in American history.
