The U.S. can deport the Palestinian-born leader of Wisconsin’s largest mosque on the grounds that he is a foreign policy threat, an immigration judge ruled Wednesday, while rejecting allegations that he lied on his green card application.

Salah Sarsour was detained in Milwaukee in March by U.S. Immigration and Customs Enforcement officers. A federal judge ordered Sarsour’s release in June, saying he raised a “substantial” claim that the Trump administration was targeting him for speaking out against Israel and advocating for Palestinian rights.

Sarsour said in a statement that the ruling was “deeply disappointing,” but that he intends to appeal.
