The Justice Department is pursuing an aggressive effort to strip U.S. citizenship from individuals accused of obtaining it through fraud, marking what officials describe as a historic escalation under the Trump administration’s acting attorney general, Todd Blanche.

The push is part of a broader strategy to expand denaturalization enforcement dramatically by shifting cases away from specialized immigration litigators and into the 93 U.S. attorneys’ offices nationwide. Officials are aiming to increase both the volume and speed of cases, targeting individuals accused of concealing criminal histories, entering sham marriages, or otherwise misrepresenting key facts during the naturalization process.
