First cabinet of Donald Trump

Donald Trump assumed office as the 45th president of the United States on January 20, 2017, and his first term ended on January 20, 2021. The president has the authority to nominate members of his cabinet to the United States Senate for confirmation under the Appointments Clause of the United States Constitution.

Before confirmation and during congressional hearings a high-level career member of an executive department heads this pre-confirmed cabinet on an acting basis. The cabinet's creation was part of the transition of power following the 2016 presidential election.

This article documents the nomination and confirmation process for any successful or unsuccessful cabinet nominees of the first Trump administration. They are listed in order of creation of the cabinet position (also used as the basis for the United States presidential line of succession).
