Trump Appoints Marco Rubio as National Security Adviser Amid Growing Cabinet Roles

President Donald Trump has fired National Security Adviser Mike Waltz, citing his hawkish stance on Russia and security lapses, and nominated him as the next U.S. Ambassador to the United Nations, filling a long-vacant post. In the interim, Trump has appointed Secretary of State Marco Rubio to also serve as National Security Adviser, adding to his already crowded portfolio that includes acting administrator of USAID and acting archivist of the United States. The move has been met with widespread commentary and humor on social media and among political figures, who note Rubio's accumulation of high-profile roles. Despite the revolving door of appointments, insiders suggest Trump is the primary driver of U.S. foreign policy and prefers loyalists who follow his directives over independent-minded experts. The shakeup is the first major Cabinet change since Trump’s second term began, and reflects ongoing instability and unconventional staffing practices in the administration. Meanwhile, Trump has publicly praised Rubio’s problem-solving abilities, signaling strong confidence in his multi-tasking leadership.
