Washington (CNN) Rep. Alexandria Ocasio-Cortez on Sunday sharply criticized President Donald Trump for implying that she and other freshman House Democrats were not natural-born American citizens, saying the President is "angry because (he) can't conceive of an America that includes us."

"You are angry because you can't conceive of an America that includes us. You rely on a frightened America for your plunder," Ocasio-Cortez tweeted, adding in another message that the country she "come(s) from" is the United States.

Mr. President, the country I "come from," & the country we all swear to, is the United States.



But given how you've destroyed our border with inhumane camps, all at a benefit to you & the corps who profit off them, you are absolutely right about the corruption laid at your feet. https://t.co/HLKQCotR8T — Alexandria Ocasio-Cortez (@AOC) July 14, 2019

"But you know what's the rub of it all, Mr. President? On top of not accepting an America that elected us, you cannot accept that we don't fear you, either. You can't accept that we will call your bluff & offer a positive vision for this country. And that's what makes you seethe," she wrote.

A group of Democrats, who are women of color and have been outspoken about Trump's immigration policies, were among those who last week condemned the conditions of border detention facilities . Some also testified last week in front of a House Oversight and Reform committee hearing, explaining what they saw during their tour of the facilities housing migrants amid a border crisis.
