Secretary of State Marco Rubio has taken on the dual roles of national security adviser and secretary of state in a significant shake-up of U.S. foreign policy under President Donald Trump. This move marks a departure from Rubio’s previous positions and reflects Trump’s overhaul of longstanding policies. Rubio, a former Trump rival, has aligned himself with the “America First” foreign policy agenda, focusing on initiatives that prioritize American interests over traditional advocacy for foreign aid and democracy promotion. Since his confirmation, Rubio has led a radical reorganization of the State Department, including the dismantling of the U.S. Agency for International Development and substantial job cuts. He has also overseen controversial immigration agreements and visa revocations impacting foreign students. Despite initial doubts about his tenure, Rubio has proven resilient in his roles, managing both the State Department and the National Security Council simultaneously. While State Department officials were surprised by his additional appointment as acting national security adviser, Rubio’s duties as secretary of state are expected to continue with some delegation of NSC responsibilities. The move positions Rubio alongside Trump’s personal friend and special envoy Steve Witkoff, reflecting a trend of officials taking on multiple roles in the administration. Rubio’s expanded responsibilities have garnered praise for his reliability and competence, highlighting his ability to navigate a challenging and dynamic political landscape.
