President-elect Donald Trump has a 75-day transition period ahead of him to build out his team before Inauguration Day on Jan. 20.

One item at the top of Trump’s to-do list will be figuring out how to fill roughly 4,000 government positions with political appointees. These roles include positions from the secretary of state and other Cabinet positions to those selected to serve part time on boards and commissions. About 1,200 of those appointments require Senate confirmation, which shouldn’t be a problem for Trump as Republicans are on pace to have at least a two-seat majority in the chamber.
