Rex Tillerson

Transition officials said that Trump wanted a secretary of state who is good at making deals. Former Exxon Mobil CEO Rex Tillerson certainly fits that bill. He also seems to share another goal with his new boss: working more closely with Russia. The Texas native began his career at Exxon as an engineer in 1975 and took over as CEO in 2006. Though he has no government experience, the 64-year-old oversaw a company that has operations in 50 countries around the world and has worked closely with Russian President Vladimir Putin. In 2011, he struck a deal with a Kremlin-controlled oil company to drill in the Arctic, but the project was put on hold after the U.S. and Europe imposed sanctions on Russia over its actions in Ukraine, according to the Wall Street Journal. According to The Hill, Tillerson believes in man-made climate change and supports the Paris climate agreement that Trump opposes.

Steve Mnuchin

Mnuchin was Trump’s campaign finance chairman. He worked at Goldman Sachs for 17 years and was ultimately a partner at the investment firm. After leaving Goldman Sachs, Mnuchin created his own hedge fund and financed movies like the X-Men franchise and Avatar. From 2009 to 2015, Mnuchin was the head of a California bank that has been referred to as a “foreclosure machine.” The bank foreclosed on an estimated 36,000 homeowners, according to NPR’s John Ydstie. Mnuchin does not have any government experience.

Retired Gen. James Mattis

Mattis is a retired Marine Corps general, famous for both his blunt talk and his engaging leadership in recent U.S. conflicts. He served as the commander of U.S. Central Command, overseeing the wars in Iraq and Afghanistan, from 2010 to 2013. Nicknamed "Mad Dog," Mattis is known for an ability to connect with troops, his intellectualism — quoting Roman philosophers at will — and controversial statements, like when he said "it's fun to shoot some people" in a 2005 speech discussing fighting the Taliban. Mattis advocated against isolationism recently, and warned Donald Trump against embracing the use of torture. To serve in this civilian post, Mattis needed a congressional waiver from a federal law that requires a member of the military to wait seven years after leaving the armed forces before serving as secretary of defense.

Sen. Jeff Sessions

The 69-year-old Republican senator from Alabama was one of the first lawmakers to ally himself with candidate Trump. He embraces a hard-line anti-immigration platform and approach to fighting crime. Sessions is a controversial pick. His appointment to a federal judgeship was denied by the Senate in 1986 after lawyers testified he had used racially charged language, including calling the NAACP "un-American."

Rep. Ryan Zinke

Ryan Zinke is the sole U.S. representative for Montana. He was elected in 2014 and won a second term this year. Zinke is also a 23-year veteran of the U.S. Navy SEALS, which he retired from in 2008. His service included a stint as a commander of the elite SEAL Team 6, which is best known for killing Osama bin Laden in 2011. Zinke is currently on the House Armed Services Committee and the Committee on Natural Resources. A self-proclaimed fifth-generation Montanan, Zinke told The New York Times in a 2015 interview that he resented “regulation being formulated and forced in Washington from bureaucrats that have never been to Montana.” Zinke has been seen as the likely GOP challenger to Sen. Jon Tester, an incumbent Democrat up for re-election in 2018. The seat is a top target for Republicans, and Zinke’s nomination throws into question how the party will proceed in its efforts to defeat Tester.

During the 2016 election, he served on Trump’s agricultural advisory committee. After meeting with Trump in New York City, he told reporters that the two men talked about “using the productivity of American farmers all across the land to sell our products internationally with fair trade deals." In 2007, he faced criticism as governor when he prayed for rain outside the state Capitol during a drought. Perdue does not yet have a committee hearing scheduled.

Wilbur Ross

The 79-year-old billionaire investor is the chairman and chief strategy officer, as well as the founder, of the private equity firm WL Ross and Co. (He later sold the firm to Invesco but is still involved with it.) According to NPR’s Marilyn Geewax, Ross made his name restructuring failing companies using borrowed money. In 1990, he was instrumental in helping Trump’s Taj Mahal casino emerge from bankruptcy. In 2002, Ross joined several troubled U.S. steel companies together to create the International Steel Group. He cut costs and employees and flipped the company, selling it to Mittal Steel in The Netherlands. Shortly after his company purchased the Sago Mine in West Virginia, an explosion there killed 12 miners. A former Democrat, Ross has been a loyal Trump supporter. In a June interview with CNBC, he said that the U.S. needed a “more radical, new approach to government.”

Bush, he was appointed to the National Labor Relations Board in late 2002.

Dr. Ben Carson

Former 2016 presidential candidate and retired neurosurgeon Ben Carson endorsed Trump less than a week after he dropped out of the presidential race in early March. Throughout the general election, Carson was an avid Trump defender. When a tape of Trump bragging about groping women came out, Carson urged Republicans not to be “distracted” by the revelation. Originally from Detroit, Carson was the director of pediatric neurosurgery at Johns Hopkins Hospital in Baltimore, Md., for nearly 30 years. He initially pulled himself out of the running for a position in Trump’s Cabinet; a Carson adviser told The Hill that he did so because he didn’t have government experience and didn’t want to “take a position that could cripple the presidency." But Carson has cited his own personal story as the son of a single mother who grew up in Detroit as experience he would bring to the agency that oversees affordable housing in inner cities.

Rick Perry

Rick Perry was the governor of Texas from 2000 to 2015. He also ran for the Republican presidential nomination twice, in 2012 and 2016, but was unsuccessful in both bids. In 2011, during a Republican debate during his first presidential campaign, Perry famously couldn’t recall one of three government departments he said he would abolish if president. It was the Department of Energy, which he is now picked to run. Though Texas is an oil state and Perry has advocated for fewer restrictions in that industry, the majority of the Department of Energy’s resources are actually devoted to managing the country’s nuclear weapons, according to The New York Times. After dropping out of the 2016 election, Perry initially endorsed Texas Sen. Ted Cruz and called Trump a “cancer on conservatism” and a “barking carnival act.” Trump responded on Twitter, saying Perry “should be forced to take an IQ test before being allowed to enter the GOP debate.” After suspending his second presidential campaign, Perry had a brief stint on the reality competition show Dancing with the Stars.

Notably, however, he is not a veteran himself and, if confirmed, would be the first head of the VA who hasn’t served in the armed forces.

Kelly served in the Middle East, where he led combat forces in Iraq's Anbar Province. Kelly lost a son, Marine Lt. Robert Kelly, in combat in Afghanistan. Kelly, 66 at the time of his retirement, was the nation's longest serving general. He is a native of Boston.

Robert Lighthizer

Robert Lighthizer was a deputy U.S. trade representative during the Reagan administration. As NPR’s Mara Liasson reported, Lighthizer is an advocate for a more protectionist position on trade and has supported a tougher stance on trade with China. He was also the treasurer for former Sen. Bob Dole’s 1996 presidential campaign. In 2008, Lighthizer wrote an op-ed in The New York Times, where he criticized Republican presidential nominee John McCain’s stance on free trade and said that true conservatives of the past have “sometimes supported protectionism and at other times they leaned toward lowering barriers.” Lighthizer is now a partner at the law firm Skadden Arps, where he has focused on trade litigation and helped U.S. companies access foreign markets. In the Trump transition team statement announcing his appointment, Lighthizer said, “I am fully committed to President-elect Trump’s mission to level the playing field for American workers and forge better trade policies which will benefit all Americans.” Lighthizer does not yet have a confirmation hearing scheduled.
