Kristi Noem, who previously served as Secretary of the Department of Homeland Security, has assumed a new position within President Donald Trump’s administration, joining the State Department as a senior adviser. The appointment was confirmed Friday, October 16, 2026, placing Noem under the leadership of Deputy Secretary of State Christopher Landau. This transition marks another shift in responsibilities for Noem, following her departure from a Cabinet-level role earlier this year.
The move comes approximately seven months after President Trump replaced Noem as the head of the Department of Homeland Security. In March, the President selected Markwayne Mullin to lead the department, concluding Noem’s tenure in one of the administration’s most prominent Cabinet positions. Following her departure from DHS, Noem was assigned as a special envoy to the Shield of the Americas, a regional initiative designed to strengthen cooperation between the United States and countries across Latin America and the Caribbean.
Noem’s role as special envoy was intended to last six months, an appointment that expired in September, shortly before the United Nations General Assembly. In a social media post, Noem explained that the six-month duration of her previous assignment had always been the plan. The State Department confirmed Thursday that Noem will continue to be involved in efforts to coordinate regional security cooperation, maintaining her focus on diplomatic engagement and security partnerships throughout the Western Hemisphere.
The Shield of the Americas initiative, where Noem served as special envoy, was established to bolster relationships between the United States and several nations in the Caribbean and Latin America. Its primary focus areas include economic cooperation, collective efforts to combat international drug cartels, and addressing other regional security challenges. During her time as special envoy, Noem actively participated in diplomatic discussions with foreign governments and collaborated with officials involved in the administration’s broader regional strategy.
Despite maintaining a lower public profile since leaving Homeland Security, Noem has continued to represent the administration in meetings with international leaders. Her recent engagements included a meeting with Ecuadorian President Daniel Noboa, highlighting the administration’s ongoing diplomatic outreach in South America. She also held discussions with Ecuadorian and Colombian diplomats in Washington during September. These meetings were followed by additional engagements with regional leaders on the sidelines of the United Nations General Assembly.
Her continued activities suggest that the transition to the State Department will allow her to maintain focus on several of the same diplomatic and security priorities that characterized her previous assignment. This decision also ensures Noem’s continued presence within the Trump administration, despite her earlier removal from the Homeland Security leadership position. Her new role as a senior adviser places her under Deputy Secretary of State Landau, who plays a key role in coordinating the department’s diplomatic operations.
Unlike her previous Cabinet position, the senior adviser role does not grant Noem direct control over a major federal department. Instead, she will contribute to the administration’s foreign policy efforts through the State Department in an advisory capacity. The State Department has not yet announced whether Noem’s latest assignment will have a predetermined expiration date or outlined additional responsibilities beyond her existing regional security work.
Noem’s transition marks the latest development in her continued service under President Trump. Her responsibilities have shifted from leading a significant domestic security department to engaging in international diplomacy and fostering regional cooperation. This move underscores the administration's emphasis on retaining experienced personnel for its foreign policy objectives, particularly within the strategically vital Western Hemisphere.
