Trump hit Waters, who is one of his fiercest Democratic critics, at a campaign rally for GOP congressional hopeful Rick Saccone in Pennsylvania on Saturday.

"And Maxine Waters, a very low IQ individual. Did you ever see her?" the president said.

" 'We will impeach him. We will impeach the president. But he hasn't done anything wrong. It doesn't matter, we will impeach him.' She's a low IQ individual. She can't help it. She really is. 'We will impeach him.' But we have Maxine Waters and plenty of others," he continued.

Waters shot back at Trump during an MSNBC interview on Sunday.

"This is not only typical of him, this is what this con man does. He diverts attention from himself by attacking others, but this business about Stormy [Daniels] is not going to go away," Waters said, referring to Trump's alleged affair with the adult-film star.

"He can call us all the names that he wants to call us, but you know our special counsel, [Robert] Mueller, is connecting the dots, and last night in a speech I said that if for some reason Mueller does not get him, Stormy will," she said.
