After six months of aggressive immigration enforcement and promises to focus on deporting violent criminals, the Trump administration has arrested and detained a small fraction of the undocumented immigrants already known to Immigration and Customs Enforcement as having been convicted of sexual assault and homicide, internal ICE data obtained by NBC News shows. The data is a tally of every person booked by ICE from Oct. 1 through May 31, part of which was during the Biden administration. It shows a total of 185,042 people arrested and booked into ICE facilities during that time; 65,041 of them have been convicted of crimes. The most common categories of crimes they committed were immigration and traffic offenses.
