WASHINGTON, July 20 — The figure that matters in sizing up the U.S. Department of Justice Antitrust Division is $500,000. That was the sum Congress specifically earmarked for antitrust enforcement on February 25, 1903. The bottom line: The division that today reviews billion-dollar media mergers began with a half-million-dollar line item.
Congress doubled down March 3, 1903, creating the position of Antitrust Attorney General. By 1904, the DOJ Register listed just two professional staffers working on antitrust matters.
The division itself wasn’t formally established until 1919, under Attorney General A. Mitchell Palmer’s reorganization of the Department of Justice. The core mission then — enforcing the Sherman Act and the Clayton Act — remains the same today.
Structure and Leadership
The division is led by an assistant attorney general appointed by the president and confirmed by the Senate. The current AAG is Gail Slater. Investors will note that the division’s organizational chart includes a Media, Entertainment, and Communications Section, which directly reviews large media deals for potential antitrust violations.
That section operates within the division’s civil enforcement arm. As of January 24, 2025, the full organizational structure includes the Office of the Assistant Attorney General, civil enforcement sections (including the Media, Entertainment, and Communications Section), criminal sections and offices, the Economic Analysis Group, and policy units.
Among the criminal offices are the Chicago Office and the San Francisco Office — both of which also have civil enforcement responsibilities.
Split Enforcement Authority
By the numbers of its legal mandate, the Antitrust Division shares civil enforcement authority with the Federal Trade Commission under both the Sherman Act and the Clayton Act. It holds exclusive authority over criminal antitrust enforcement under the Sherman Act. That means the division alone can bring criminal charges for price-fixing, bid-rigging, and other offenses.
A controversial decision in January 2013 closed four of the division’s criminal antitrust offices. The move was intended to save money.
Career prosecutors criticized it, arguing that shutting local offices would increase travel expenses and reduce the detection of local conspiracies. The bottom line on that controversy: Cost savings on office space may have come at the expense of enforcement reach against smaller, regionally based cartels. The criticism from career staff was pointed.
They argued that traveling from distant offices to investigate local conspiracies would cost more, not less, and that on-the-ground presence in specific markets mattered for detecting violations early. The division’s leadership at the time chose the closures anyway.
What to watch next: The division’s Media, Entertainment, and Communications Section will remain a focal point for investors as large media consolidation deals continue to face scrutiny. The 2013 office closures also remain a live issue for career staff. Now in its second century of operation, the Antitrust Division is still shaped by that original $500,000 mandate — and by the decisions made along the way about how to enforce it.
