The Justice Department has issued a memorandum telling prosecutors to consider stripping U.S. citizenship from naturalized immigrants convicted of serious crimes, building upon efforts that began just months before the end of President Donald Trump‘s first term five years ago.

In a June 11 memo, Assistant Attorney General Brett Shumate directed attorneys in the Civil Division to “prioritize and maximally pursue denaturalization proceedings in all cases permitted by law and supported by the evidence.” The memo outlines 10 categories of offenses that will trigger priority review, including terrorism, war crimes, human trafficking, financial fraud, and gang activity.
