Rossano Rubikundi made offensive remarks to the Post about the wife of the US president and said his relationship with Ivana was still good, but his feelings were not the same for her children.
Rubikundi said he believed Donald Trump Jr., Ivanka Trump and Eric Trump were "disgusting" and called them "scum".
The 47-year-old Italian said he had never benefited from the Trump family's wealth, and that Ivana was very respectful of him, but he did not feel like Donald Jr., Eric Trump and Ivanka Trump.
"These people worship money, they have no hearts, they are waste," he said.
"Donald son is a fool, they're nothing, they're disgusting, we're talking about stupid kids, except Ivanka, they're scum, before they say anything about me, I'll wash their mouths with soap!
