US President-elect Donald Trump on Tuesday said Tesla and SpaceX CEO Elon Musk will lead a so-called Department of Government Efficiency alongside American entrepreneur Vivek Ramaswamy.

"Together, these two wonderful Americans will pave the way for my Administration to dismantle Government Bureaucracy, slash excess regulations, cut wasteful expenditures, and restructure Federal Agencies - Essential to the 'Save America' Movement," Trump said in a statement.
