The U.S. Department of Homeland Security has confirmed that Corey Lewandowski, a longtime Trump ally and former 2016 campaign manager, has officially departed from his unpaid advisory role at the agency. The exit marks another significant shift in the administration's rapidly evolving national security structure.
Lewandowski's departure closely follows the removal of former DHS Secretary Kristi Noem earlier this month. A department spokesperson confirmed he "no longer has a role" at DHS, effectively closing the chapter on his informal advisory position. While Lewandowski was recently spotted alongside Noem during diplomatic engagements in Guyana, the State Department has been clear that he holds no official position there either.
Noem, meanwhile, has moved into a newly created diplomatic role as special envoy for the "Shield of the Americas," a hemispheric security initiative designed to extend U.S. influence across the Western Hemisphere. Lewandowski will not be part of that effort.
Filling the leadership vacuum at DHS is former U.S. Senator Markwayne Mullin, who earned Senate confirmation last Tuesday. Mullin's appointment signals a shift toward more structured, operationally focused leadership after weeks of personnel turbulence. Analysts expect the new secretary to prioritize institutional stability and move quickly on border security and federal contracting decisions that have been in a holding pattern.
The wave of high-level changes at DHS has drawn attention from both policy circles and financial markets, particularly investors tracking government spending on border enforcement and homeland security infrastructure. With Mullin now at the helm, stakeholders are watching closely for his first major policy directives, which are expected to shape department priorities well into the second half of 2026.
The restructuring underscores the Trump administration's ongoing efforts to consolidate leadership and reduce administrative friction across key federal agencies.
