A new president means that there are some huge staff changes for the White House. Donald Trump is announcing his new cabinet members as the days wind down to his inauguration. Here are some brief introductions to the new White House staff.

Jeff Sessions is President-elect Donald Trump’s pick for Attorney General. The Attorney General is the head of the United States Department of Justice. Sessions is a senator of Alabama. Before he held this position, he was a U.S. attorney and state attorney general. For Head of Homeland Security, the future president has chosen John Kelly. Kelly was previously the head of U.S. Southern Command.

Next up on the roster is Rex Tillerson for Secretary of State. The Secretary of State is advisor to the president when it comes to foreign affairs. Tillerson is ExxonMobil’s CEO and has no other political experience. Head of the Central Intelligence Agency (C.I.A.) will be Mike Pompeo. Pompeo is Kansas’ G.O.P. representative.

Betsy De Vos is the pick for Education Secretary. She is a multi-billionaire education reformer, but has no other experience in education. Elaine Chao is the pick for Transportation Secretary. Chao has held this position before under George H.W. Bush and has a lot of experience with the Department of Transportation.  

For Secretary of Defense, James Mattis is the president-elect’s pick. Mattis is a retired Marine General, whose experience in the military should offer a great insight for his position. Former candidate for the 2016 election, Ben Carson, is the pick for Housing and Urban Development Secretary. Though an experienced brain surgeon and politician, Ben Carson is a controversial choice because he has no experience in housing or urban development. Finally, Trump’s pick for Commerce Secretary is Wilbur Ross. The Commerce Secretary is in charge of promoting American businesses and industry. Ross is an experienced businessman.

The Senate confirmation hearings for the appointment of Cabinet members has already begun.  Most presidential appointees are confirmed routinely, without need for debate.
