The Trump administration has launched a major reorganization of the U.S. fight against drug traffickers and other transnational criminal groups, setting out a strategy that would give new authority to the Department of Homeland Security and deepen the influence of the White House.

The administration’s plans, described in internal documents and by government officials, would reduce federal prosecutors’ control over investigations, shifting key decisions to a network of task forces jointly led by the FBI and Homeland Security Investigations, the primary investigative arm of DHS.

Current and former officials said the proposed reorganization would make it easier for senior officials like Miller to disregard norms that have long walled off the White House from active criminal investigations.
