President-elect Donald Trump has announced a handful of new Cabinet picks. On Tuesday, he named billionaire Steven Mnuchin to be treasury secretary. Mnuchin has deep ties on Wall Street, including working as a partner for Goldman Sachs, where his father also worked. Mnuchin’s hedge fund also played a role in the housing crisis, after it scooped up the failing California bank IndyMac in 2008. Under Mnuchin’s ownership, IndyMac foreclosed on 36,000 families, particularly elderly residents trapped in reverse mortgages. Mnuchin was accused of running a “foreclosure machine.” The bank, which was renamed OneWest, was also accused of racially discriminatory lending practices. In 2015, Mnuchin sold the bank for $3.4 billion—$1.8 billion more than he bought it for.
