The Trump administration has removed two top officials from the Justice Department’s Antitrust Division, which promotes competition and sues to prevent monopolies. Bill Rinner and Roger Alford were fired for insubordination amid disputes over recent corporate mega-mergers, including T-Mobile’s purchase of UScellular and Hewlett Packard Enterprise’s $14 billion acquisition of Juniper Networks. CBS News reports the HP merger was approved only after Attorney General Pam Bondi’s chief of staff overruled the head of the Antitrust Division, Gail Slater. Democrats are demanding an investigation into the firings. Minnesota Senator Amy Klobuchar wrote, “The Antitrust Division has long worked to enforce the law to fight monopoly power, but these attorneys may have been fired for doing just that.”
