Donald Trump never claimed to know everything, but he did promise to assemble a Cabinet that does. Over the past months, our President-elect and his transition team have been working incessantly to assemble a Presidential Cabinet while pacifying outrage during this pivotal time in our nation. The Cabinet plays an imperative role in ensuring the welfare of our nation, as they advise him in all inquiries. Over the years, various positions were removed, but the 15 department heads that remain today have withstood the test of time. Here is a summation of some of the political figures who will advise Donald Trump on nearly every decision he will make as President:

Secretary of State: Rex Tillerson
In a world of 7.4 Billion people, Rex Tillerson was named #24 on Forbes’ compilation of “The Most Powerful People in the World” for 2015 and 2016. Tillerson is one of Trump’s more controversial Cabinet picks due to his former title (as of December 31, 2016) as CEO of ExxonMobil for 10 years. Similar to Trump, supporters of Tillerson believe his entrepreneurial success makes up for his lack of public service and military experience. His role as an Exxon executive raises conflicts of interest questions, because he will carry out the President’s foreign policies through the State Department and Foreign Service. Politically, he is a longtime contributor to Republican campaigns and strongly opposes sanctions against Russia due to his close business ties with Vladimir Putin. Those business ties proved to be a concern at Tillerson’s Senate Confirmation Hearing, where GOP figures like Marco Rubio pressed the Texan on Russia’s alleged human rights abuses.

Secretary of Defense: James Mattis
On December 1, 2016, Donald Trump announced that James Mattis will run the Pentagon as the chief authority over the United States Department of Defense. Born September 8, 1950, Mattis is a retired United States Marine Corps general who has commanded several military commands. During the Iraq war, Mattis instructed the I Marine Expeditionary Force, United States Marine Forces Central Command, and 1st Marine Division. In addition, Mattis commanded the United States Joint Forces Command from 2007-2010 and was later appointed by President Obama to replace General Petraeus as U.S. Central Command. Politically, he believes the settlement situation in the West Bank is “unsustainable” and supports a two-state solution. In the past, he has praised Secretary John Kerry’s approach to peace in the Middle East.

Attorney General: Jeff Sessions
Perhaps most controversial of all the Cabinet picks is Senator Jefferson Sessions of Selma, Alabama. Sessions’ political career began in 1975 when he was Assistant United States Attorney in the Office of the U.S. Attorney for the Southern District of Alabama. When Sessions stood before the Senate in his Confirmation Hearing on January 10, it certainly was not his first; in 1986, Reagan nominated Sessions to be a judge of the U.S. District Court for the Southern District of Alabama. Session’s 1986 hearing before the Senate went down in flames, as four Department of Justice lawyers who had worked with Sessions testified that he made racially offensive remarks. This ultimately led to Sessions becoming the second nominee to the federal judiciary in 48 years whose nomination was killed by the Senate Judiciary Committee. At his hearing on January 10, the 1986 confirmation hearing was the primary topic of discussion. Politically, Sessions is extremely conservative both fiscally and socially, to the extent that he earned a zero rating from the Human Rights Campaign.

Overall, the Cabinet of Donald Trump is the wealthiest in American history, at a collective net worth of $11 Billion, and the least racially diverse in recent history, earning it negative comments from policy experts.
