Marco Rubio Formally Takes Dual Role as Secretary of State and National Security Adviser
Washington, Wednesday, 23 September 2026.
President Donald Trump signed a commission making Marco Rubio permanent national security adviser alongside his secretary of state post, making him the first dual-role holder since Henry Kissinger.
Executive Consolidation of National Security Roles
President Donald Trump has officially signed a commission appointing Secretary of State Marco Rubio as the permanent national security adviser, a move confirmed by White House officials on September 22, 2026 [1][5]. This decision formally consolidates two of the nation’s premier foreign policy and foreign intelligence coordination roles under a single official, marking a significant shift in executive leadership structure [1]. The appointment was publicly confirmed by multiple administration officials and reported across major news outlets on September 22, 2026, solidifying Rubio’s position after a period of interim service [3][6]. For global markets and executive leadership, this unprecedented dual role streamlines foreign policy decision-making within the administration, potentially signaling a more unified approach to international trade and geopolitical diplomacy [1][2].
Historical Precedent and Role Expansion
Marco Rubio is the first person to hold both the Secretary of State and national security adviser roles simultaneously since Henry Kissinger served under President Richard Nixon in the 1970s [1][2]. Henry Kissinger previously established the historical precedent for holding both roles, serving as national security adviser starting in 1969 and becoming secretary of state in 1973 [2]. Beyond these primary roles, Rubio has held multiple additional responsibilities during President Trump’s second term, including acting administrator of the U.S. Agency for International Development (USAID) and acting archivist of the United States [2][4]. This accumulation of responsibilities highlights a centralized approach to governance within the current administration, with Rubio noted by President Trump as someone who gets problems solved [1].
Timeline of Appointment and Previous Tenure
Rubio had previously been serving in the national security adviser role in an acting capacity following the departure of former national security adviser Mike Waltz in May 2025 [1][3]. Waltz left the position more than a year ago after becoming embroiled in the scandal known as Signalgate, where sensitive military plans were discussed on an encrypted messaging app [1][3]. While some reports indicate the commission was signed on Tuesday, September 15, 2026, the public confirmation and formal announcement occurred on September 22, 2026 [2][3]. A White House official confirmed to media outlets that the signed commission makes Rubio’s dual role official, transitioning him from acting to permanent status [5][6].
Political Implications and Future Focus
Despite speculation linking Rubio to a potential 2028 Republican presidential contender list, the Secretary of State stated earlier this month that he has no plans to launch a White House bid [1][2]. In an interview with Colombian news station RCN translated by NBC News, Rubio emphasized his focus, stating, I’m not a candidate for anything right time [1][3]. This clarification comes alongside similar positioning by Vice President Vance, who is also frequently mentioned in potential candidacy discussions [1]. The consolidation of power within the national security apparatus suggests a focus on immediate geopolitical challenges rather than domestic political campaigning for the upcoming election cycle [2][6].
