During October 2019 criminal prosecutions referred to the Department of Justice (DOJ) by immigration enforcement agencies fell 4.2 percent, continuing their sharp decline over the past year. The DOJ reported 8,315 new prosecutions were filed in October 2019[1] compared with 13,286 a year ago - down 37.4 percent. Those findings are based on case-by-case records obtained through Freedom of Information Act (FOIA) lawsuits by the Transactional Records Access Clearinghouse (TRAC) at Syracuse University.
