The State Department confirmed Thursday that Kristi Noem is no longer serving as President Donald Trump's special envoy for the Shield of the Americas initiative.

A department official stated that Noem's envoy designation expired last month, shortly before the United Nations General Assembly. She remains involved in the administration's efforts to coordinate security cooperation across the Western Hemisphere.

"She is now a senior advisor to Deputy Secretary Landau and continues to work on the Shield of the Americas portfolio," the official said.

Noem was appointed to the envoy role in March after President Trump removed her as homeland security secretary. Senator Markwayne Mullin replaced her in that Cabinet position.

The Shield of the Americas is a coalition of the United States and multiple Caribbean and Latin American countries focused on economic cooperation, anti-cartel enforcement, and other security matters.

During her time as envoy, Noem met with Ecuadorian President Daniel Noboa and participated in discussions with regional diplomats in Washington and on the sidelines of the U.N. General Assembly. President Trump publicly thanked her for her work at a gathering of coalition leaders.

The transition keeps Noem in the administration focused on the same Western Hemisphere security priorities. This adjustment maintains her engagement on border security and regional stability issues that have long been priorities for conservative administrations.

Her continued involvement in these areas provides additional experience in international diplomacy and coalition-building at a time when Republican leaders emphasize strong national security policies. Such a profile could expand future electoral opportunities aligned with those priorities should Noem look to make a run for another political office in the future.
