President-elect Donald Trump has narrowed the field of candidates for Treasury secretary to Steven Mnuchin and Jonathan Gray, multiple sources tell CNN. Mnuchin, 53, is a former Wall Street exec turned Hollywood producer. And Gray, 46, is a billionaire in charge of real estate for the Blackstone private equity firm. Both Mnuchin and Gray would be seen as political moderates. Gray is a registered Democrat and Mnuchin has contributed to both parties. Last week, Trump's first picks for senior positions were seen as very conservative.
