Donald Trump's campaign announced Thursday that Steven Mnuchin, chairman and CEO of private investment firm Dune Capital Management LP, will serve as Trump's national finance chairman for the general election. Instead of self-funding his general election campaign as he did his primary run, Trump, the presumptive GOP nominee, has revealed that he will be creating a "world-class finance organization" to actively raise funds to compete with Hillary Clinton's fundraising powerhouse. Trump's campaign says that Mnuchin, also formerly a partner at Goldman Sachs, will bring the necessary financial experience to what's expected to be a $1 billion campaign.
