Donald Trump again tried to boast about his intelligence, but at least one member of his family wasn’t buying it. 

Mary Trump, a niece who has been highly critical of the former president, told MSNBC’s Lawrence O’Donnell on Monday that her uncle is a “black hole of need.” He needs compliments to fill the void and yet he knows people are only telling him what he wants to hear. 

“And also because he knows it isn’t true,” said Mary Trump, who is a psychologist. “He knows he’s a deeply unintelligent person. He knows that he’s severely damaged and has severe limitations so he’s always trying to fill a need that is unfillable.” 

Over the weekend, Trump bragged about his intelligence as he explained how he once passed a test designed to detect cognitive decline. He also claimed genius runs in his family.
