Two recent federal criminal actions show the Justice Department continuing to press aggressively in both competition and health care enforcement. In Oklahoma City, a federal jury convicted Sioux Erosion Control Inc., along with one executive and one employee, for participating in a roughly $100 million bid-rigging and price-fixing conspiracy tied to public transportation contracts. In a separate matter, prosecutors unsealed a racketeering indictment accusing four alleged members of the “War Room” of orchestrating a $12 million Medicaid fraud scheme.

Taken together, the matters are a reminder that DOJ is treating criminal antitrust and health care fraud as parallel priority areas, with consequences that extend well beyond the charged defendants.

The Department of Justice has unveiled one of the year’s largest coordinated health care enforcement actions: the 2026 National Health Care Fraud Takedown, which includes charges against 455 defendants nationwide, among them 90 physicians and other licensed professionals. Prosecutors say the cases involve more than $6.5 billion in alleged false claims, underscoring the scale of the government’s continuing focus on fraud in federal health care programs.

The sweep was coordinated across U.S. Attorneys’ Offices, with participation from DOJ’s Criminal Division, HHS-OIG, CMS, and other federal and state enforcement partners.

The Justice Department’s latest announcement around health care fraud enforcement is one of the more consequential legal developments for companies operating in regulated industries this week. According to the reporting referenced, federal authorities have highlighted a major enforcement push targeting fraud schemes tied to health care billing and reimbursement, underscoring that prosecutors continue to view the sector as a core enforcement priority.

For legal professionals, the story is not simply about another round of criminal charges.

The Department of Justice has announced a broader fraud-enforcement push that includes creation of a new West Coast Health Care Fraud Strike Force covering California, Arizona, and Nevada. Although the announcement is not tied to a single newly filed case, it is a meaningful development for healthcare companies, executives, and defense counsel because it signals concentrated criminal and civil scrutiny in some of the nation’s largest healthcare markets.

The initiative, led through the DOJ Fraud Division and highlighted by Assistant Attorney General Colin McDonald, points to a more coordinated enforcement approach among federal prosecutors in the region.
