Hoda Muthana, who left the US to join ISIL in 2014, was in a protracted legal battle to return to the country.
The United States Supreme Court refused to hear an appeal by a woman who had left the US to join ISIL (ISIS), but then decided she wanted to return to the country.
The judges of the High Court on Monday refused without comment to appeal the appeal of Hoda Muthanawho was born in New Jersey in October 1994 as a Yemeni diplomat and grew up near Birmingham, Alabama.
Muthana left the US to join ISIL in 2014, apparently after becoming radicalized online.
While abroad, the government determined that she was not a U.S. citizen and withdrew her passport, citing her father’s status as a diplomat at the time of her birth. Her family sued to make her return to the US possible.
A federal judge ruled in 2019 that the U.S. government correctly determined Muthana was not a US citizen despite her birth in the country. Children of diplomats are not entitled to birthright citizenship.
The family’s lawyers appealed, arguing that her father’s status as a diplomat assigned to the United Nations ended before she was born, making her a citizen automatically.
Muthana surrendered to the US-backed Syrian Democratic Forces as ISIL fighters were losing the last of their self-proclaimed caliphates in Iraq and Syria and going to refugee camps.
Muthana said she regretted her decision to join the group and wanted to return to the U.S. with her toddler, the son of a man she met while living with the group. The man later died.
Her current whereabouts are not clear.
Family lawyer Christina Jump of the Constitutional Law Center for Muslims in America did not immediately return an email from The Associated Press news agency on Tuesday asking for comment.
The decision to revoke her passport was taken under former President Barack Obama.
The case received widespread attention when former President Donald Trump tweeted about it, saying he had instructed the Secretary of State not to allow her back into the country.
