In an episode early in Donald Trump’s career, his New York real estate company was sued by the federal government for discriminating against potential black renters. After a lengthy legal battle, it ultimately agreed to wide-ranging steps to offer rentals to nonwhites.

The little-remembered case provides crucial context for the current discussion centering on Trump and race. The celebrity businessman made news last month when he declared, “I have a great relationship with the blacks. I’ve always had a great relationship with the blacks.”

He has recently come under fire for attacks on President Obama that critics have described as racially tinged. CBS anchor Bob Schieffer, for example, said Wednesday there is  “an ugly strain of racism” in Trump’s recent (baseless) accusations that President Obama should not have been admitted to Columbia. Also yesterday, Trump told a black reporter, unprompted, “Look I know you are a big Obama fan.”

The discrimination case began in the earliest days of Trump’s career, when he was still in his 20s.

Fred Trump, Donald’s father, was, unlike his son, a self-made man. He made his fortune by building thousands of units of middle-class housing in Brooklyn and Queens. But in the early 1970s, Donald was made president of the family company.

One of Donald’s first challenges came in October 1973, when the Justice Department hit the Trump Organization with a major discrimination suit for violating the Fair Housing Act. The Times reported:

… the Government contended that Trump Management had refused to rent or negotiate rentals “because of race and color.” It also charged that the company had required different rental terms and conditions because of race and that it had misrepresented to blacks that apartments were not available.

The journalist Gwenda Blair reported in her 2005 Trump biography that while Fred Trump had sought to combat previous discrimination allegations through “quiet diplomacy,” Donald decided to go on the offensive. He hired his friend Roy Cohn, the celebrity lawyer and former Joseph McCarthy aide, to countersue the government for making baseless charges against the company. They sought a staggering $100 million in damages.

A few months after the government filed the suit, Trump gave a combative press conference at the New York Hilton in which he went after the Justice Department for being too friendly to welfare recipients. He “accused the Justice Department of singling out his corporation because it was a large one and because the Government was trying to force it to rent to welfare recipients,” the Times reported. Trump added that if welfare recipients were allowed into his apartments in certain middle-class outer-borough neighborhoods, there would be a “massive fleeing from the city of not only our tenants, but communities as a whole.”
