A federal judge on Friday blocked President Trump 's administration from enforcing his new travel ban against a Syrian family looking to escape their war-torn homeland by fleeing to Wisconsin.

The ruling is likely the first by a judge since Trump issued a revised travel ban on Monday, according to a spokesman for the Washington state attorney general, who has led states challenging the ban.

The Syrian man filed a new complaint on Friday afternoon, alleging the new order is still an anti-Muslim ban that violates his freedom of religion and right to due process. He asked Conley to block its enforcement against his family.

U.S. District Judge William Conley said there were daily threats to the Syrian man's wife and child that could cause "irreparable harm." He issued a temporary restraining order barring enforcement against the family. The order doesn't block the entire travel ban. It simply prevents Trump's administration from enforcing it against this family pending a March 21 hearing.

“The court appreciates that there may be important differences between the original executive order, and the revised executive order. ... As the order applies to the plaintiff here, however, the court finds his claims have at least some chance of prevailing for the reasons articulated by other courts,” Conley wrote.

A Syrian Muslim man who was granted asylum and settled in Wisconsin has been working since last year to win U.S. government approval for his wife and 3-year-old daughter to leave the devastated city of Aleppo and join him here. The man, who is not identified because of fears for his family's safety, filed a federal lawsuit in Madison in February alleging Trump's first travel ban had wrongly stopped the visa process for his family.

After the Trump ban was blocked the first time, the approval process restarted for the Syrian family and they're now preparing to travel to Jordan for visa interviews at the U.S. embassy, the last step before U.S. customs officials decide whether to issue them visas. But the family doesn't have dates for the interviews yet and Trump's new travel ban goes into effect March 16, stirring fears that the process could halt again before visas are issued, according to the Syrian man's attorneys.

Government attorneys argued during a teleconference with Conley on Friday that the new ban may not apply to this family anyway, although they did not go into details. There are various exemptions and waivers in the new ban including some that give consular officers flexibility to decide cases. Conley acknowledged that the family's situation is murky but still issued the order, saying the man seems to have a good chance of winning the case.

The U.S Justice Department is defending the ban. Spokeswoman Nicole Navas said agency attorneys were reviewing the Syrian man's complaint and declined further comment on it and Conley's order.

Trump issued an executive order in January banning travelers from seven predominantly Muslim countries, including Syria, from entering the United States. U.S. District Judge James Robart in Washington state blocked the entire order on Feb. 3.

The revised order issued Monday removed Iraq from the list of countries and would temporarily shuts down the refugee program. Unlike the first order, the new ban would not affect current visa holders and removes language that would give priority to religious minorities. Hawaii filed a lawsuit challenging the new ban Wednesday; other states with Democratic attorneys general plan to sue next week.

According to the Syrian man's lawsuit, he fled his country to avoid near-certain death at the hands of two military factions, one a Sunni-aligned group fighting against President Assad 's regime and another group fighting in support of Assad. The pro-Assad forces thought he was sympathetic to the other side and the anti-Assad army targeted him because he was a Sunni and traveled to pro-Assad areas to manage his family's business.

Both sides tortured him and threatened to kill him, the lawsuit said. The pro-Assad forces also threatened to rape his wife. He came to the United States in 2014 and was granted asylum last year. He then began filing petitions seeking asylum for his wife and daughter.
