President-elect Donald Trump’s transition team has spent the last several months building a short list of industry titans and conservative activists who could comprise his Cabinet, according to a Politico report.

The transition team started with a mandate to hire from the private sector when possible. Trump is also expected to reward his election team, who stood by him during the presidential campaign. However, the transition team remains at this point tight-lipped about cabinet posts and has declined to confirm speculations.

Following is a list of potential  picks for Cabinet Posts, compiled by Politico based on their conversations with policy experts, lobbyists, academics, congressional staffers and those close to Trump:

Agriculture Secretary:  Possible picks  included Sid Miller, the current secretary of agriculture in Texas; Kansas Governor Sam Brownback; former Nebraska Governor Dave Heineman; former Georgia Governor Sonny Perdue; and former Texas Governor Rick Perry.  Also under consideration are Charles Herbster, Republican donor and agribusiness leader, and Mike McCloskey, a major dairy executive in Indiana.
