The New York Times – no paywall: “It was driven with a frenetic focus by Mr. Musk, who channeled his libertarian impulses and resentment of regulatory oversight of his vast business holdings into a singular position of influence. Without ceding control of his companies, the richest man in the world has embedded his engineers and aides inside the government’s critical digital infrastructure. Already, his Department of Government Efficiency, or DOGE, has inserted itself into more than 20 agencies, The New York Times has found. Mr. Musk’s strategy has been twofold. His team grabbed control of the government’s human resources agency, the Office of Personnel Management, commandeering email systems to pressure civil servants to quit so he could cull the work force. And it burrowed into computer systems across the bureaucracy, tracing how money was flowing so the administration could choke it off. So far, Musk staff members have sought access to at least seven sensitive government databases, including internal systems of the Social Security Administration and the Internal Revenue Service. Mr. Musk’s transformation of DOGE from a casual notion into a powerful weapon is something possible only in the Trump era. It involves wild experimentation and an embrace of severe cost-cutting that Mr. Musk previously used to upend Twitter — as well as an appetite for political risk and impulsive decision-making that he shares with President Trump and makes others in the administration deeply uncomfortable.”
