Rep. Maxine Waters (D-Calif.) predicted Sunday that President Trump's alleged affair with adult film star Stormy Daniels will be his downfall if special counsel Robert Mueller's investigation isn't.

"But this business about Stormy is not going to go away," she told MSNBC. "If for some reason Mueller does not get him, Stormy will. So we know that this is going to go on."

Trump allegedly had an affair with Daniels, whose real name is Stephanie Clifford, more than a decade ago. His lawyer, Michael Cohen, paid her $130,000 just before the 2016 election as part of a nondisclosure agreement about the affair.

Daniels has since filed a lawsuit alleging the nondisclosure agreement is invalid because Trump never signed it.

Waters has been a fierce and vocal critical of Trump's rhetoric and policies. She was among 60 Democrats who voted in December to launch impeachment proceedings against the president.

Trump has been critical in response, saying Saturday night at a rally that "she's a low IQ individual."

Waters told MSNBC on Sunday that Trump likes to attack women in particular.

"It seems that he's identifying and picking up more and more women that he's attacking. This is not only typical of him, this is what this con man does. He diverts attention from himself by attacking others," she said.

Waters vowed she would not dial down her criticisms of Trump.

"I'm not gonna run from it, I'm not intimidated by by him, and so he can keep calling names. I've got plenty for him. As a matter of fact, everybody knows he's a con man, he's been a con man all of his life," she said.
