“I hired a contractor for demolition. He had Polish workers for his force; that’s all it was. And by the way, the laws were totally different,” Trump told Fox News’s Chris Wallace on "Fox News Sunday."

Trump was forced to answer questions about the lawsuit, which involved Polish workers, after his GOP rival Sen.

Trump dismissed the criticism from Rubio, whom he repeatedly called “Little Marco,” on the lawsuit, which is from the 1980s.

“Thirty-five years ago? That’s the best they could do?” Trump said during a fiery, often rambling exchange. 

When asked if Trump was aware of the illegal immigrants working on his building — citing reports that some of the men slept on the construction site — Trump insisted it was a "fairly common practice."  

"In construction, many, many people sleep on the site," he said.
