Seems clear to me now that the theory is going to be that she was NOT related to the person she claimed was her father, so she could NOT get derivative citizenship via his naturalization whether he ever was naturalized or not. She has been an undocumented alien in the US her entire life because her real father remained in Great Britain when she came to the U.S. with a different family who lied about her being their daughter. This is why they wanted DNA of her sister, and already had DNA of her husband/brother. There is reporting that this all kicked off recently over a group text message on her sister's phone -- LIKELY obtained in connection with the fraud investigations in Minneapolis that involve her sister. THAT's why they wanted her phone so badly -- to find the same message on her phone. She's probably in the group chat that was found on her sister's phone. The message must reveal some information about them not being part of the same family. If she acknowledged knowing that was the case, then she has lied numerous times as an adult about what she knew about her lineage and whether she was naturalized. Lying about citizenship is a federal crime.
