President-elect Donald Trump doesn't have the traditional group of Washington insiders and donors to pull from for his Cabinet appointments but his transition team has spent the past several months building a list of executives from various industries in the private sector as well as conservative activists who could ultimately comprise one of the more eclectic presidential Cabinets in modern history.

While many Washington "insiders" refused to support his campaign, which probably helped him in the end, Trump is also expected to reward the surrogates who stood by him, including Newt Gingrich, Rudy Giuliani and Chris Christie.

So far, the Trump campaign and transition teams have been quiet about their potential cabinet picks but the speculation is starting to swirl.  Per Politico, here's some insight, based on conversations with policy experts, lobbyists, academics and congressional staffers on who might be picked for the key jobs:

Secretary of state

Former House Speaker Gingrich, a leading Trump supporter, is a candidate for the job, as is Corker, current chairman of the Senate Foreign Relations Committee. The Tennessee senator has said he'd "strongly consider" serving as secretary of state.

Trump is also eyeing former U.S. Ambassador to the United Nations John Bolton.
