President-elect Donald Trump has nominated Senator Marco Rubio as Secretary of State and South Dakota Governor Kristi Noem for Secretary of Homeland Security. Rubio's appointment highlights his foreign policy experience, while Noem's selection signals a tougher immigration stance with the inclusion of immigration hardliners like Tom Homan and Stephen Miller in significant roles. Trump's administration continues to take shape with other key appointments, including Mike Waltz as national security adviser and Elise Stefanik as UN ambassador. This cabinet reflects Trump's commitment to strict immigration policies and maintaining strong foreign relations.
