President-elect expected to pick Marco Rubio for secretary of state and Mike Waltz for national security adviser

Donald Trump has chosen a pair of establishment Republicans from Florida for senior roles in his administration as he builds a national security team that looks more hawkish than the isolationist America First brand of foreign policy that he has championed in public.

Trump was expected to select the senator Marco Rubio as his secretary of state, the US’s top diplomat, and has asked the congressman Mike Waltz, a retired Green Beret known as a China hawk, to become his national security adviser, a powerful role that would help shape his policies on the conflicts in Ukraine and Gaza, as well as around the world.
