The ABC's PM program reports that loyal allies of Donald Trump continue to land plum roles in his new cabinet.

Tech billionaire Elon Musk will lead a new Department of Government Efficiency, along with entrepreneur Vivek Ramaswamy, who at one point was competing against Donald Trump to become the Republican presidential candidate.

One appointment raising eyebrows is Fox News host and army veteran Pete Hegseth, who will become the Secretary of Defence.

USSC Director of Research Jared Mondschein was interviewed by the ABC about these apointments.
