In the days since Donald Trump won the presidential election, his Trump Tower in New York has been a revolving door for his transition team.

Political and business elite as well as several family members have been spotted walking in and out of the building since last week.

Many are having meetings with Trump as the President-elect's transition team helps decide who will be by his side in the White House.

While Trump's camp have not yet revealed the choices he's made for his Cabinet, several politicians and businessmen, including former rival Ted Cruz and New York Mayor Bill de Blasio, have made appearances at Trump Tower.

Vice president-elect Mike Pence took over the transition leadership for Trump's journey to the White House from Chris Christie last week and together they have been 'reviewing a number of names for key jobs' as lists for the leadership positions begin to narrow, Trump spokesman Jason Miller said.

On Wednesday, appearances were made by Steven Mnuchin, national finance chairman of President-elect Donald Trump's campaign, Sen Jeff Sessions, retired Lt General Michael Flynn, New York Jets Owner Robert 'Woody' Johnson and more.
