President Donald Trump quickly waved off a question about Rep. Alexandria Ocasio-Cortez (D., N.Y.) on Monday, waving his hand and saying "who cares."

Ocasio-Cortez said there was "no question" Trump was a racist in a recent "60 Minutes" interview, and a reporter asked Trump about it as he took questions at the White House.

"Congresswoman Ocasio-Cortez called you a racist," a reporter said.

"Who did?" Trump asked.

"Congresswoman Ocasio-Cortez," the reporter said.

"Who cares? Geez," Trump said, moving onto another question.

Trump answered questions from reporters for several minutes before leaving for New Orleans, where he will address a farmers' convention.

Ocasio-Cortez, the youngest woman ever elected to Congress, is driving more Twitter conversation than any American politician other than Trump. A Democratic socialist with an ambitious agenda and quick to hit back at conservative and media critics, she has amassed a huge following since coming into the public's attention last summer with her upset primary victory over former Rep. Joe Crowley (D., N.Y.).

In spite of Trump's dismissiveness, she declared victory afterward on Twitter, saying it was clear she had gotten to him.

"I bartended for *years* in New York City. I understand guys like this like the back of my hand. We got under his skin," she tweeted.
