Trump settled on Tillerson to lead the State Department after a long and high-profile search.
"Rex knows how to manage a global enterprise, which is crucial to running a successful State Department, and his relationships with leaders all over the world are second to none. I can think of no one more prepared and no one more dedicated to serve as secretary of state at this critical time in our history," Trump said in a Dec. 13 statement.
Tillerson has ample experience in international negotiations. However, he also has a history of close ties to Russia and its President Vladimir Putin, which came up during his confirmation hearings.
Here's everything you need to know about this administration's secretary of state.
Name: Rex Wayne Tillerson
Age: 64 (born March 23, 1952)
Family: Married, with four children
What he used to do: Tillerson joined ExxonMobil in 1975 as a production engineer. He rose through the ranks, becoming general manager in 1989 and production adviser to the Exxon Corp. in 1992. In 1998 he became vice president of Exxon Ventures and president of Exxon Neftegas Limited, where he was responsible for the company's holdings in Russia, including the Caspian Sea and the Sakhalin Island area. In August 2001 he was promoted to senior vice president of the ExxonMobil Corp. and became CEO in 2006. He has no previous public sector experience.
Education: B.S., civil engineering, University of Texas at Austin
Relationship with Trump: Tillerson emerged as a late contender on what seemed to be an ever expanding list of possible nominees for secretary of state. He met with Trump on Dec. 6, and the two convened for a second time on Dec. 10. Tillerson has a history of donating to Republicans in recent years. According to Federal Election Commission filings, he donated $50,000 to Mitt Romney's presidential victory fund in 2012 and gave $5,000 to Right to Rise, a super PAC backing Jeb Bush, in August 2015. But his FEC records do not show any donations to Trump during the 2016 campaign.
Trump and Exxon relationship: Trump owned ExxonMobil stock. His 2015 financial disclosure filing lists $50,000 to $100,000 worth of assets in ExxonMobil.
Things you might not know about him: In 2015, when he was CEO of ExxonMobil, Tillerson was No. 20 on Forbes' most powerful people list.
He has a strong relationship with Russia:
Tillerson's business relationship with Russia dates to the 1990s, when he assumed responsibility for all of ExxonMobil's holdings there. In 2011 the company forged a deal with Russian oil company Rosneft, which at that time was 75 percent owned by the Russian government. The deal gave ExxonMobil access to Arctic oil deposits, and Putin attended the signing ceremony. In 2013 the two companies expanded their partnership. That year, Tillerson received the Order of Friendship from Putin.
In 2014, after Russia annexed Crimea, Exxon was forced to halt the deal because of U.S. sanctions. Although ExxonMobil put out a press release saying it was "winding down" its operations after the sanctions, Tillerson reportedly called sanctions ineffective at a 2014 shareholders meeting.
"We do not support sanctions, generally, because we don't find them to be effective unless they are very well implemented comprehensively, and that's a very hard thing to do," he said at that meeting, according to The Dallas Business Journal.
An ABC News search found that Rosneft sanctions are still listed in a Treasury Department database of sanctions.
Tillerson's relationship with Russia was a focal point in his confirmation hearings with the Senate Foreign Relations Committee last month.
He referred to economic sanctions against Russia as a "powerful tool" and rejected the claims that he and ExxonMobil, under his leadership, lobbied against them to advance the company's financial interests.
When asked by Sen. Marco Rubio, R-Fla., whether Putin should be labeled a war criminal, Tillerson said, "I would not use that term." Rubio pressed, citing Russia's brutal bombing campaign targeting civilians and hospitals in rebel-held areas of Syria, and Tillerson said, "I do not have sufficient information to make that claim."
He did acknowledge that Putin was behind the hackings intended to influence the U.S. presidential election.
Although Tillerson has acknowledged climate change is a problem, ExxonMobil was the subject of controversy at its shareholders meeting last year for rejecting resolutions that would have pushed the company's resources toward renewable energy, according to a Washington Post article.
"We have to have some technology breakthroughs, but in the meantime, just saying 'turn the taps off' is not acceptable to humanity," he said at the meeting, according to The Washington Post.
At least five attorneys general were investigating the company's climate change policies as of spring 2016, including New York's Eric Schneiderman, who oversaw a now settled lawsuit against Trump University, according to the Post.
Tillerson's confirmation has already drawn the ire of environmental groups like the Sierra Club and Greenpeace.
"It's unconscionable that the Senate confirmed an oil executive to be America’s ambassador to the world. And yet that's exactly what they have done," Sierra Club Executive Director Michael Brune wrote in a statement.
