He also shared harsh criticism of the Democratic Party as a whole.
"They're imploding," Trump told Fox News' Sean Hannity Tuesday night, adding: "They have no message. You see the head of the (Democratic National Committee), who is a total whack job."
Trump's "not even people" remark quickly evoked comparisons on social media to Hillary Clinton's "basket of deplorables" comment made about President Trump's supporters during the 2016 campaign.
Trump -- one of President Donald Trump's five children -- also said Democrats are obstructing the current administration.
"They lost the election that they should have won because they spent seven times the amount of money that my father spent. They have no message so what do they try and do? They try and obstruct a great man, they try and obstruct his family, they come after us viciously, and its truly, truly horrible," Trump said."
