The U.S. government has been hit with four painful losses at antitrust trials recently, including cases against UnitedHealth Group and Cargill, but legal experts do not expect the Biden administration's regulators to slow its efforts.
In fact, the Justice Department and Federal Trade Commission (FTC) have vowed to press on aggressively.
The top competition lawyer at the Justice Department, Jonathan Kanter, told lawmakers on Sept. 20 that "part of the job that we have before us is to litigate cases and to take risks when it's appropriate and necessary to defend the American public, particularly in areas such as health care."
He added: "We are not going to back down from bringing meritorious cases."
The department has merger fights underway in industries like airlines, publishing, national security and residential locks.
The Justice Department lost two merger fights last month, failing to stop Minnetonka-based UnitedHealth Group's $13 billion bid to buy Change Healthcare, which closed on Monday, and U.S. Sugar's deal for Imperial Sugar Co.
FTC Chair Lina Khan noted the agency had sued to block six mergers outright in the past year.
"Congress has tasked us with stopping unlawful mergers," she said in a statement to Reuters. "If we determine that a merger would violate the law, we have a responsibility to act, and we will not shrink from that duty."
