Three weeks out from Donald Trump’s victory in the 2016 presidential campaign, his transition team has already begun rolling out a series of top staff hires and Cabinet picks.
There are just over 4,000 political appointments to be made by the incoming Trump administration. About 1,200 of them will require Senate confirmation — the Cabinet secretaries and their deputies, as well as those appointees who will head independent agencies, like the CIA and EPA, for instance. These nominees will go through a vetting process and Senate hearing.
Here’s a list of the top Cabinet and staff announcements Mr. Trump’s team has made so far, beginning with the most recent:
Defense Secretary: Retired Gen. James Mattis
Mattis, a retired Marine Corps general and decorated war veteran, is a known opponent of the current White House policy on Iran, arguing that nothing has been done to counter Iran’s threat to stability in the Middle East. He has been a vocal critic of the Iran nuclear deal, saying earlier this year that it was “an arms control agreement that fell short.”
If confirmed, Gen. Mattis, 66, is likely to deter Trump from engaging in isolationism and negotiations with Russian President Vladimir Putin. Mattis has doubts about Russia’s intentions, saying it wants “to break NATO apart.”
The retired general also opposes waterboarding, a torture technique that Mr. Trump has promised he would legalize in the fight against ISIS.
Mattis, however, could face a legal roadblock to his senate confirmation. The law specifically prohibits a person from serving as chief of the Defense Department “within seven years after relief from active duty as a commissioned officer of a regular component of an armed force.” Mattis retired in 2013. The Trump administration will have to seek a congressional waiver for the appointment, allowing Mattis to serve.
Commerce Secretary: Wilbur Ross
An ally during Trump’s election campaign, the 79-year-old Ross is the billionaire chairman of WL Ross & Co., an investment firm that specializes in corporate restructurings.
During the campaign, Ross often appeared on business news shows to explain Trump’s positions, sometimes softening or downplaying the candidate’s protectionist trade policies.
Ross built his estimated $2.9 billion fortune by snapping up distressed industrial businesses, such as steelmaker LTV. Ross might be best known to voters as the owner of Sago Mine, a West Virginia coal mine where a dozen miners lost their lives in a 2006 explosion. He called that tragedy “the worst week of my life.”
Treasury Secretary: Steven Mnuchin
Mr. Trump announced Wednesday morning that he’d selected Mnuchin, who served as the national finance chairman of Trump’s presidential campaign, for the top Treasury Department job. This has been widely expected since Mr. Trump won the race for the White House. Earlier this month, Mr. Trump’s transition recommended Mnuchin for the post.
Mnuchin is a veteran of the finance world, spending 17 years at Goldman Sachs. Others who were reportedly considered for the job include JP Morgan Chase & CO CEO Jamie Dimon and Rep. Jeb Hensarling (R-Texas).
Transportation Secretary: Elaine Chao
Elaine Chao, who served as labor secretary under President George W. Bush, is the first Asian-American woman to ever hold a Cabinet-level position. She served in the role from 2001 to 2009 — the only member of Bush’s Cabinet to serve through his entire eight years in the White House.
Before serving as labor secretary, Chao ran the United Way of America, was director of the Peace Corps and served as deputy treasury secretary under President George H.W. Bush. She is married to Senate Majority Leader Mitch McConnell (R-Kentucky).
Health and Human Services Secretary: Tom Price
Price, a five-term congressman hailing from the Atlanta suburbs, is the chairman of the House Budget Committee. He’s an orthopedic surgeon by trade, and was an early supporter of Trump’s presidential candidacy.
Price has also been a strong advocate, like his fellow Republicans, of repealing Obamacare. Price favors expanding health savings accounts and providing tax credits for purchasing health coverage.
Education Secretary: Betsy DeVos
Betsy DeVos, a prominent charter school advocate from Michigan, has also chaired the state’s Republican party. She currently serves as chairwoman of the American Federation for Children, a school choice advocacy group.
She and her husband also head up the Dick and Betsy DeVos Family Foundation, which has supported projects like the West Michigan Aviation Academy, a public charter school in Grand Rapids and the Compass Film Academy, a Christian film school in Michigan.
The billionaire DeVos family also owns the NBA team, the Orlando Magic. Dick DeVos’ father founded Amway.
Attorney General: Jeff Sessions
Sessions has been one of Mr. Trump’s closest and most consistent allies, and he was the first senator to announce his support for the president-elect. An architect of Mr. Trump’s immigration, counterterrorism and trade policies, Sessions was also considered for secretary of defense.
Appointing him the nation’s top prosecutor is sure to be controversial, though: he’s been through the Senate confirmation process before, with mixed success. He did make it through a Republican-controlled Senate in 1981, when they approved him to be the U.S. attorney for the Southern District of Alabama. But then, nominated for a federal judgeship in 1986, Sessions, R-Ala., was dogged by accusations that he had made racist comments while serving as U.S. attorney.
CIA Director: Mike Pompeo
Pompeo, a Kansas congressman first elected during the tea party wave of 2010, serves on the Energy and Commerce and House Intelligence committees, and he also served on the House Select Benghazi Committee.
According to his website, he’s the former CEO of an oilfield company and also of an aerospace company he founded. And Pompeo is also a Harvard-trained lawyer who graduated first in his class at West Point.
National Security Adviser: Michael Flynn
Flynn, a lifelong Democrat, is a former head of the Defense Intelligence Agency (DIA) -- he was one of the highest-ranking national security officials supporting Trump, whom he also informally advised him on foreign policy during the primary campaign. He is also known to be a proponent of stronger ties with Russia, as well as a critic of President Obama.
Trump had at one point reportedly considered Flynn for vice president before choosing Mike Pence.
