“They are absolutely ridiculous,” he said. “We never have discriminated, and we never would. There have been a number of local actions against us, and we've won them all. We were charged with discrimination, and we proved in court that we did not discriminate.”

Mr. Trump and his father, Fred C. Trump, the principal stockholder and corporate board chairman, were also named as defendants. They are required to respond to the complaint within 20 days. The Trump family has been in the real‐estate business for more than 40 years.

In Washington, J. Stanley Pottinger, assistant attorney general in charge of the Justice Department's civil‐rights division, termed the suit the second major rental discrimination action begun by the department in the last two years.

The first involved Samuel J. Lofrak, one of the country's largest builders. The Justice Department had charged racial discrimination in the renting of 21,000 Lefrak‐controlled apartments in 150 buildings in Brooklyn and Queens.

Agreement With Lefrak

That case was resolved on Jan. 28, 1971, in an agreement between the Justice Department and the Lefrak Organization. Lefrak promised to prohibit discrimination in apartment rentals, and subsequently fifty black families were assisted in moving into predominantly white buildings.
