Mr. Musk's Department of Government Effectiveness is expected to target the Department of Homeland Security in the coming days, seeking large-scale layoffs across its various agencies, which could include the Secret Service, according to market sources. The Department of Homeland Security is preparing for possible large-scale layoffs, the sources said. No final decision has been made, and the final size and scope of the cuts have not yet been determined. A senior DHS official said the department was "determined to eliminate decades of government waste at the expense of the American taxpayer. Across the Department of Homeland Security, we will eliminate non-mission critical positions and bureaucratic obstacles that impede our mission to protect our homeland."
