After President Trump directed a series of racist tweets at Reps. Alexandria Ocasio-Cortez, Ilhan Omar, Rashida Tlaib and Ayanna Pressley  on Sunday, the group of freshman congresswomen known as the “the Squad” rebuked the president for his bigoted remarks and vowed to continue fighting his cruel attacks on immigrants and other vulnerable communities.

“This is what racism looks like,” tweeted Pressley, a Massachusetts congresswoman, after Trump said the freshman Democrats should “go back” to the countries “from which they came.”

Trump’s attack was met with a flood of outrage. By Monday morning, the hashtag #RacistPresident reached the top of Twitter’s trending list.

Omar, a Minnesota Democrat and the only member of “the Squad” not born in the United States, said Trump is “the worst, most corrupt and inept president we have ever seen.”

“You are stoking White nationalism because you are angry that people like us are serving in Congress and fighting against your hate-filled agenda,” Omar, a Somali refugee, tweeted in response to the president’s attack.

Mr. President, as members of Congress, the only country we swear an oath to is the United States. Which is why we are fighting to protect it from the worst, most corrupt and inept president we have ever seen, Omar tweeted.

The president similarly said the progressive congresswomen are “viciously telling the people of the United States, the greatest and most powerful nation on earth, how our government is to be run.”

“Why don’t they go back and help fix the totally broken and crime infested places from which they came,” Trump wrote. “Then come back and show us how it is done.”

Tlaib, a Palestinian American, was the first of the targeted congresswomen to hit back at the president’s remarks.

“Want a response to a lawless and complete failure of a president? He is the crisis,” Tlaib tweeted. “His dangerous ideology is the crisis. He needs to be impeached.”

Ocasio-Cortez followed Tlaib with a series of tweets blasting Trump for relying “on a frightened America for [his] plunder.”

“Mr. President, the country I ‘come from’, and the country we all swear to, is the United States,” wrote the New York Democrat. “But given how you’ve destroyed our border with inhumane camps, all at a benefit to you and the corp[orations] who profit off them, you are absolutely right about the corruption laid at your feet.

“You are angry because you can’t conceive of an America that includes us,” Ocasio-Cortez added. “You won’t accept a nation that sees healthcare as a right or education as a #1 priority, especially where we’re the ones fighting for it. You can’t accept that we will call your bluff and offer a positive vision for this country. And that’s what makes you seethe.”
