What Trump's cabinet could look like

Unlike traditional presidential campaigns, the Trump camp started late with setting up a transition team and once it did it wasn't a fully fleshed out apparatus like that of his rival Hillary Clinton.

That definitely changed after their candidate scored a stunning victory. Team Trump is now in full transition mode, as evidenced by Friday's announcement that Vice President-elect Mike Pence would now take the helm of the transition effort, replacing Chris Christie, the embattled governor of New Jersey.

The Trump team also launched an official transition website aptly named www.greatagain.gov, after Trump's campaign slogan, along with a new Twitter handle dedicated to the transition effort.

While transition preparations are gaining steam, little concrete is known so far about a key element of the new Trump administration - the people taking over the most important positions.

Rocky relationship

Trump's rocky relationship with large parts of the Republican party establishment has only complicated efforts to fill vital cabinet slots, as many Republicans with governmental experience had openly opposed the GOP candidate and rejected any possible role in a Trump administration already during the campaign.

One thing that does appear certain is that two of Trump's closest allies, former House Speaker Newt Gingrich and former New York Mayor Rudy Giuliani, in some way or another will play important roles in the new administration.

Chris Christie, himself a former presidential candidate until recently, was also expected to land a position in a Trump administration. But possible legal ramifications of the so called "Bridgegate" scandal could make Christie a liability, therefore his chances to play a key role have significantly decreased.         

So here are five key positions for a Trump administration and people mentioned in the media to be considered for them.

Secretary of State

John Bolton, former US ambassador to the United Nations

Newt Gingrich, former speaker of the House of Representatives

Bob Corker, senator from Tennessee and chairman of the Senate's Committee on Foreign Relations
