You may have been following the case of Shamima Begum, who has had her British citizenship revoked after travelling to Syria to join ISIS as a 15-year-old.
A similar story has now emerged from the United States, as Donald Trump has said he will bar an American-born woman who left to join ISIS in 2014 from returning to the country.
Hoda Muthana, who is now 24, claims she made a "big mistake" in going to Syria four years ago and that she was brainwashed online.
She now wants to return to her family in Alabama, along with her 18-month-old son.
However, both Trump and Secretary of State Mike Pompeo are claiming that Muthana is not a US citizen, despite being born and raised there.
But should she be re-admitted so that she can face the US justice system?
