Federal immigration officials have apprehended the head of Wisconsin’s largest mosque, accusing him of hiding a past conviction related to attacks on Israeli targets and providing false information on his U.S. immigration paperwork.

The leader of the Islamic Society of Milwaukee, Salah Salem Sarsour, was detained by U.S. Immigration and Customs Enforcement (ICE) during a focused operation earlier this week, as reported by the Department of Homeland Security (DHS).

A statement from DHS released on Thursday revealed that Sarsour, a citizen of Jordan, had been previously convicted in Israel for launching a Molotov cocktail at the residences of Israeli military personnel and for attempting to acquire weapons and ammunition.

The agency claims that Sarsour did not reveal his criminal history on immigration documents and unlawfully secured permanent resident status in the United States.

“Salah Salem Sarsour is a convicted terrorist who attacked the homes of Israeli armed forces with Molotov cocktails. This individual from Jordan falsely obtained legal status in the U.S. by lying on his green card application,” stated DHS Acting Assistant Secretary Lauren Bis.

Fox News’ Brooke Taylor reported that, according to ICE, Sarsour eventually became a green card holder in 1998 under President Bill Clinton after lying on his application.

In a statement to FOX 6 Milwaukee, ICE said it worked with the U.S. Marshals Service to arrest Sarsour.

The Islamic Society of Milwaukee has also created a fundraising page to support Sarsour.

“Br. Salah is being targeted on the basis of his Palestinian and Muslim background, and his advocacy for Palestinian rights,” the fundraiser says, in part. “We know this fight for Br. Salah is part of a larger trend of attacks on immigrants that whittle away at democratic norms and legal protections for everyone. That is why this fight is a fight for all of us.”

Sarsour has been the board president of the Islamic Society of Milwaukee, the largest Islamic organization in the state, for five years.

At a crowded news conference, boisterous supporters chanted to free Sarsour.

“He was targeted because of one thing, because he dared stand up to the Israeli army,” Othman Atta, one of Sarsour’s attorneys, told the crowd. “And he was not a U.S. citizen.”

A diverse group of religious leaders in attendance called Sarsour a valuable community member.

“This appears to be just the latest example of how this administration seeks to silence opposition and intimidate those who speak and act differently,” said the Rev. Paul D. Erickson, bishop of the Greater Milwaukee Synod of the Evangelical Lutheran Church in America.

Milwaukee Mayor Cavalier Johnson called Sarsour’s detainment “an outrage.”

“He is a legal permanent resident. There is no substantive evidence he has done anything wrong,” Johnson said Thursday in a post on X. “This is another example of overreach and harm from the U.S. immigration authorities.”

Sarsour is being held at a county jail in Indiana. His attorneys have filed a petition seeking his release.
