Donald Trump has turned to a veteran of the investment bank he frequently criticized on the campaign trail to head up his finances for the presidential campaign.

Trump named Steven Mnuchin, a former partner at Goldman Sachs GS, +0.01% , as his national finance chairman. Mnuchin is chairman and chief executive officer of Dune Capital Management.

During the campaign, Trump often criticized Sen. Ted Cruz for his links to the bank because of loans used to finance Cruz’s Senate campaign.

“I know the guys at Goldman Sachs. They have total, total control over him. Just like they have total control over Hillary Clinton,” Trump said in one debate. Trump’s spokeswoman separately pointed out Cruz’s wife Heidi worked for the firm.

Clinton — who has been attacked for the paid speeches she’s made to Goldman Sachs — also has a high-ranking Goldman official in her ranks, Gary Gensler, who is the former secretary of state’s chief financial officer.

Mnuchin also has worked at Soros Fund Management, whose founder, George Soros, has funded many left-leaning causes.

Mnuchin has donated frequently to Democrats, according to data from OpenSecrets -- including to Clinton and Barack Obama.

Trump is taking a different approach to the general election than to the primaries in that he’s soliciting donations far more actively. Republican strategist Ed Rollins said on Wednesday that he’s working for a so-called Super PAC that will raise money, as well as conduct polls, run ads and conduct opposition research, for Trump.
