"Busy day planned in New York," the Republican billionaire posted on Twitter regarding his transition process, which has been cranking up to full speed since he won the presidency in a shock upset over Democrat Hillary Clinton on Tuesday.

Trump has about 70 days to put together a 15-member cabinet, and the names of several of his close advisors have been mentioned as options to fill key posts.

New Jersey Governor Chris Christie is heading the transition team, and he is believed to be in the running for attorney general, along with former New York mayor Rudy Giuliani.

On Thursday, the Trump campaign floated the idea of JP Morgan chief executive Jamie Dimon as Treasury secretary, while former House speaker Newt Gingrich was being discussed as Trump's potential White House chief of staff.

Trump assumes the presidency on Inauguration Day, January 20, 2017, and President Barack Obama has stressed that one of his main priorities is to assure a peaceful and smooth transition of power.
