Marco Rubio Expands Role to Secretary of State, USAID Administrator Under Trump

President Donald Trump has significantly expanded Secretary of State Marco Rubio's responsibilities, appointing him as interim national security adviser following the ouster of Mike Waltz, who will now be nominated as the U.S. ambassador to the United Nations. Rubio now holds four major roles: secretary of state, acting administrator of USAID, acting archivist, and interim national security adviser. The consolidation of these positions marks a notable moment of trust from Trump, who has come to rely on Rubio for resolving key issues. While Rubio's rapid accumulation of titles has raised questions about how he will manage such a broad portfolio, it underscores his ascent within Trump's inner circle and the president's confidence in his loyalty and capability. The dual-hatted arrangement is rare in modern U.S. history, with comparisons drawn to Henry Kissinger, who held both roles simultaneously five decades ago. Some within the administration were surprised by the speed and manner of the announcement, reflecting the unconventional and rapidly changing dynamics of Trump's leadership style.
