The Justice Department announced on June 8, 2026, that it filed civil denaturalization actions in multiple U.S. district courts against 17 naturalized citizens, alleging offenses including sexual abuse of a minor, wire and bank fraud, bank fraud, and drug distribution [1]. Officials characterized the simultaneous filings as the largest denaturalization effort in U.S. history [1][2]. Cases were filed across several federal districts, including Minnesota and Maryland [1].
Denaturalization actions proceed under 8 U.S.C. § 1451, which authorizes the government to seek revocation of naturalized citizenship in federal district court when citizenship was procured by concealment of a material fact or willful misrepresentation, or when the underlying naturalization was otherwise unlawful [1]. The government must establish its case by clear and convincing evidence, a standard set by the Supreme Court in Kungys v. United States (1988). The civil suits do not themselves constitute criminal proceedings, but a successful judgment strips the defendant of citizenship and can render the individual subject to removal. Deputy Attorney General Todd Blanche and Assistant Attorney General Brett Shumate were identified as key officials overseeing the initiative [1][2]. Sen. Markwayne Mullin was cited in connection with the announcement [1].
The filings represent a significant escalation of the Trump administration's immigration enforcement posture, extending pressure beyond deportation and visa revocation to reach individuals who had previously obtained full citizenship status [2]. Earlier administration enforcement actions concentrated on visa holders, parolees, and undocumented individuals; the denaturalization campaign directly targets the naturalized citizen population, a legally and politically distinct category [2]. CBS News reported that administration officials framed the effort as part of a broader commitment to enforce the conditions under which citizenship is granted [2].
The 17 civil actions are now pending before their respective district courts. Each defendant retains the right to contest the government's allegations, and litigation in individual cases could extend over months or years depending on factual complexity and appellate proceedings. No sentencing or removal consequences attach until a court enters a final judgment of denaturalization. Advocacy organizations focused on immigrant rights have not yet filed responses in court, though the scale of the announcement is likely to prompt legal challenges to the government's evidentiary bases in at least some cases [2].
