(CNN) A federal judge on Monday denied a request from the family of Hoda Muthana, an American-born woman who left Alabama to join ISIS, to expedite consideration of her case, finding there was not sufficient evidence she would be irreparably harmed.

The Trump administration has argued that Muthana is not a US citizen and is therefore not eligible to return to the country.

The lawyer for her family, Charles Swift, argued that the case was eligible for expedited consideration because Muthana, who is being held in a refugee camp in northern Syria, faced immediate harm. He said her safety and ability to leave the country were precarious, noting that she has had to change camps at least once due to ISIS threats after interviews with the media.

Swift also argued that the US withdrawal of troops from Syria puts her status at risk, but in his ruling Judge Reggie Walton suggested that risk was speculative. He noted there was uncertainty around the terms of the withdrawal, saying he didn't know when troops would pull out, whether any would remain and whether their departure would create more risk to Muthana.

Justice Department lawyer Scott Stewart claimed that Swift's arguments were speculative and pointed to Muthana's access to the media as proof that she's not in immediate harm's way. He argued that the situation that Muthana finds herself in is entirely self-imposed as the result of her joining a terrorist organization.
