On October 1, 2026, Assistant Attorney General Colin M. McDonald, head of the Department of Justice’s new National Fraud Enforcement Division, issued Directive 26-12, titled “Corporate Enforcement in the Fight Against Fraud” (memorandum). The memorandum expands on the Division’s initial set of priorities set forth in an August 13, 2026 memorandum, rearticulate these priorities, and set criteria for new and ongoing investigations against companies, while granting increased oversight responsibilities to the new Corporate Enforcement Section, formerly known as the Criminal Division’s “Fraud Section.” The memorandum directs Division prosecutors to “take an aggressive, all-tools approach to investigating and prosecuting our health care, government, tax, and trade fraud priorities,” while also committing to “firmly guard against overbroad corporate enforcement—rightly dividing between shades of corporate malfeasance—lest [the Division] interfere with legitimate business operations.”
