Karoline Leavitt can call herself whatever she wants, but it doesn’t mean she’s acting like a righteous woman … so says the mother of her nephew and godson, who was detained last month.

Bruna Caroline Ferreira appeared on Erin Burnett‘s CNN show Friday … and, she laid into the White House press secretary — telling Erin she’d want to tell Karoline, “Just because you went to a Catholic school doesn’t make you a good Catholic.”

She added, “You are a mother now. How would you feel if you were … in my shoes?” Karoline and her husband, Nicholas Riccio, welcomed their first child together in July 2024.

Ferreira also notes she and Michael Leavitt — Karoline’s brother — chose KL to be her son’s godmother instead of her own sister … almost certainly deepening feelings of betrayal.

As you know … Ferreira was arrested near Boston in mid-November — and, a Department of Homeland Security spokesperson told us Ferreira, who is from Brazil,  entered the U.S. on a B2 tourist visa that required her to leave the U.S. by June 6, 1999.

DHS also alleged she had a prior arrest for battery … and reaffirmed the administration’s commitment to deporting all people in the country illegally.

Video captured Bruna leaving her driveway … when five unmarked cars blocked her path, removed her from the car and walked her away in handcuffs.

Ferreira and Leavitt’s son reportedly lives with him full-time. Her attorney, Todd Pomerleau, told us, “Bruna had no problem whatsoever with the Leavitt family. Karoline is her son’s godmother, chosen over her own sister, and Michael Sr. is a very good father. Bruna was en route to pick up her son Michael Jr. after school like she did several days a week. He lived with her till kindergarten, but now awaits for his mother’s warm embrace.”
