When Bain Capital sought to raise money in 1989 for a fast-growing office-supply company named Staples, Mitt Romney, Bain’s founder, called upon a trusted business partner: Goldman Sachs, whose bankers led the company’s initial public offering.
When Mr. Romney became governor of Massachusetts, his blind trust gave Goldman much of his wealth to manage, a fortune now estimated to be as much as $250 million.
And as Mr. Romney mounts his second bid for the presidency, Goldman is coming through again: Its employees have contributed at least $367,000 to his campaign, making the firm Mr. Romney’s largest single source of campaign money through the end of September.
No other company is so closely intertwined with Mr. Romney’s public and private lives except Bain itself. And in recent days, Mr. Romney’s ties to Goldman Sachs have lashed another lightning rod to a campaign already fending off withering attacks on his career as a buyout specialist, thrusting the privileges of the Wall Street elite to the forefront of the Republican nominating battle.
