An Alabama woman who joined the Islamic State group in Syria won¡¯t be allowed to return to the United States with her toddler son because she is not an American citizen, the U.S. said on Wednesday. Her lawyer is challenging that claim.

In a brief statement, Secretary of State Mike Pompeo gave no details as to how the administration made their determination.

¡°Ms. Hoda Muthana is not a U.S. citizen and will not be admitted into the United States,¡± he said. ¡°She does not have any legal basis, no valid U.S. passport, no right to a passport nor any visa to travel to the United States.¡±
