The Justice Department announced Monday that it will move to revoke citizenship from 17 people nationwide, marking the latest move in the Trump administration’s unprecedented push to target naturalized citizens.

Since President Donald Trump returned to office, his administration has doubled down on its denaturalization campaign, targeting foreign-born American citizens whom it accuses of fraudulently obtaining US citizenship.

Officials say that some of the people targeted in the latest effort are accused of committing fraud and sexual abuse of a minor.

Denaturalization – the process of revoking citizenship from a naturalized US citizen – is rare and can only occur in federal court. Historically, the US revoked citizenship for a range of reasons, from lying about a person’s date of arrival, age or marital status to political reasons. During World War II, for example, the US reviewed naturalization cases of German Americans who were pro-Nazi.

Under the Biden administration, the Justice Department filed 24 denaturalization cases, according to a DOJ official. The Trump administration has already outpaced that within the last year.
