“It is unacceptable to be disrespectful of Congressman Crowley,” Ocasio-Cortez said. “He’s done some phenomenal, phenomenal work for the Bronx and Queens."

She added that Trump’s comments were “bizarre.”

Trump has been mocking Crowley, the No. 4 House Democrat and chairman of the House Democratic Caucus, over the loss.

On Tuesday, Trump tweeted that Crowley was a “big Trump hater” and should have been “nicer” and “more respectful” to him.

Trump then told a crowd at a North Dakota rally on Wednesday that Crowley “got his ass kicked by a young woman who had a lot of energy.”

The 28-year-old democratic socialist said on Wednesday that she would support impeaching Trump if she won the general election in November.
