President-elect Donald Trump on Wednesday formally nominated former Goldman Sachs banker Steven Mnuchin to be his Treasury secretary.

Mnuchin had long been considered a favorite for the Treasury position. Sources told Fox News on Tuesday that Mnuchin would be nominated. Two weeks ago, businessman and close Trump associate Carl Icahn tweeted that Trump was considering Mnuchin for the post.

The 53-year-old Mnuchin was in May appointed Trump's campaign finance chairman. Through his work, Mnuchin grew close to Trump's children and son-in-law, Jared Kushner -- a top adviser to Trump -- and worked with them on fundraising events.



The campaign raised at least $169 million, in addition to the $66 million Trump spent out of his own pocket. Though that was far short of what Hillary Clinton raised, it represented an impressive haul given that Trump didn't begin fundraising in earnest until the end of May.

If approved by the Senate, Mnuchin would follow in the tradition of two previous treasury secretaries -- Robert Rubin in the Clinton administration and Henry Paulson in George W. Bush's. All had vast Wall Street experience gained from years spent working at Goldman Sachs.



Yet unlike Rubin and Paulson and unlike President Obama's two treasury secretaries, Timothy Geithner and Jacob Lew, Mnuchin would bring no government experience to Treasury, something that could prove a hurdle in navigating the tricky politics of Washington.



After graduating from Yale in 1985. Mnuchin worked for Goldman Sachs for 17 years. His father, Robert Mnuchin, had himself worked for Goldman for three decades, becoming a partner in charge of equity trading.



The younger Mnuchin amassed his own fortune at the firm and then left in 2002. He worked briefly for Soros Fund Management, a hedge fund led by George Soros, before starting his own investment firm, Dune Capital Management.



As head of this firm, Mnuchin and other investors participated in the purchase of failed mortgage lender IndyMac in 2009 and renamed it OneWest. The failure of IndyMac in 2008 with $32 billion in assets was one of the biggest casualties of the housing bust.



Mnuchin became chairman of OneWest, which was sold to CIT Group in 2015. Before the sale, OneWest faced a string of lawsuits over its home foreclosure practices.



This month, housing advocates filed a complaint asking the Department of Housing and Urban Development to investigate OneWest for possible violations of the Fair Housing Act. The lender failed to place branches in minority communities, provided few mortgages to black homebuyers and preserved foreclosed properties in white neighborhoods while allowing similar homes in minority communities to fall into disrepair, according to the California Reinvestment Coalition and Fair Housing Advocates of Northern California.



CIT declined to respond directly to the complaint but stressed in a statement that it is "committed to fair lending and works hard to meet the credit needs of all communities and neighborhoods we serve."



Mnuchin also became a major investor in Hollywood, helping finance a number of movies, including the 2009 blockbuster "Avatar."



As treasury secretary, Mnuchin would be the administration's chief economic spokesman, serving as a liaison not only to Wall Street but also to global investors, a critical role given the trillions of dollars in treasury bonds owned by foreigners. In addition, it would be his job to sell the new administration's economic program to Congress.



Mnuchin will also oversee a sprawling bureaucracy that includes the Internal Revenue Service and the agency that issues millions of Social Security and other benefit checks each month. Treasury also runs the agency that wages the financial war on terrorism.

Earlier Tuesday, Trump officially nominated Rep. Tom Price, R-Ga., as Health and Human Services Secretary and tapped Elaine Chao, former President George W. Bush's Labor Secretary, to be secretary of transportation.

Price, a former surgeon, supports the repeal of ObamaCare and has offered a replacement that would provide tax credits to subsidize the purchase of individual and family health insurance policies. His proposal would also allow insurers to sell policies across state line, boost incentives for health savings accounts, and create high-risk pools to help individuals afford coverage, while barring assistance for nearly all abortions.

Price has emerged as a top advocate of House Speaker Paul Ryan's plan to transform Medicare from a program that supplies a defined set of benefits into a "premium support" model that would, similar to Obamacare, offer subsidies for participants to purchase health care directly from insurance companies. He also wants the Medicare eligibility age to rise to 67.

Price also backs, as does Trump, a plan by House Republicans to sharply cut the Medicaid health program for the poor and disabled and turn it over to the states to run. Like Trump and most other Republicans, Price wants federal funding withdrawn from Planned Parenthood, which has come under attack for its practice of supplying tissue from aborted fetuses to medical researchers.

If confirmed as Transportation Secretary, Chao would face many pressing issues, such as how to boost the nation's aging infrastructure so that it can accommodate population growth and not become a drag on the economy, modernizing the nation's air traffic control system, ensuring that new transportation technologies are adopted in a safe manner and responding to a surge in traffic fatalities.

After serving in the Bush administration, Chao served on the board of directors for Bloomberg Philanthropies, run by former New York City Mayor Michael Bloomberg. She resigned last year after learning the organization planned to expand an environmental initiative to shutter coal-fired power plants.

Almost 90 percent of Kentucky's electricity comes from coal, and Chao's ties to the organization were used against her husband, Senate Majority Leader Mitch McConnell, during his 2014 re-election campaign.
