President Donald Trump tweeted about the "'Progressive' Democrat Congresswomen" Sunday morning, asking them to "go back" to their "corrupt" and "broken and crime infested" countries before "telling the people of the United States [...] how our government is to be run."

Trump also tweeted that he was "sure that Nancy Pelosi would be very happy to quickly work out free travel arrangements," effectively siding with Speaker Nancy Pelosi in the infighting that has escalated between her and the four freshman congresswomen nicknamed the "Squad."

Squad members include Representatives Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts, and Rashida Tlaib of Michigan.

Of the four progressive freshmen congresswomen, only Omar was born outside the US, in Mogadishu, Somalia.

President Donald Trump tweeted Sunday morning asking the "'Progressive' Democrat Congresswomen" to "go back" to their "corrupt" and "broken and crime infested" countries. He claimed the congresswomen, most likely referring to the "Squad" of freshman progressives, were "loudly [...] and viciously telling the people of the United States [...] how our government is to be run."

Instead, Trump suggested that the congresswomen, who he tweeted "originally came from countries whose governments are a complete and total catastrophe, the worst, most corrupt and inept anywhere in the world (if they even have a functioning government at all)," should "go back and help fix" the "places from which they came."

"These places need your help badly, you can't leave fast enough," Trump tweeted, along with saying "I'm sure Nancy Pelosi would be very happy to quickly work out free travel arrangements!"

Trump tweeted amidst infighting between House Democrats, most notably between Speaker Nancy Pelosi and Representative Alexandria Ocasio-Cortez, who accused Pelosi of "explicitly singling out" the "newly elected women of color," such as when Pelosi told The New York Times that Ocasio-Cortez and the Squad "didn't have any following."

The Squad includes Ocasio-Cortez, along with Representatives Rashida Tlaib, Ayanna Pressley, and Ilhan Omar. Of the four, only Omar was born outside the US. Ocasio-Cortez was born in the Bronx borough of New York City, Tlaib was born in Detroit, Michigan, and Pressley was born in Cincinnati, Ohio.

Omar was born in Mogadishu, the capital of Somalia. On her official campaign website, Omar says she and her family fled Somalia's civil war when she was 8-years-old, living in a refugee camp in Kenya for four years before immigrating to the US and moving to the Cedar-Riverside neighborhood of Minneapolis in 1997.

Trump continued firing off tweets and retweets after his attack on the freshman congresswomen, sharing 22 retweets and tweeting "we are getting it done anyway" in a quote tweet of a supporter saying he shouldn't have to defend himself from attacks.

Pelosi responded within two hours on Twitter with the following tweet: "When @realDonaldTrump tells four American Congresswomen to go back to their countries, he reaffirms his plan to "Make America Great Again" has always been about making America white again. Our diversity is our strength and our unity is our power."

Rep. Omar responded on Twitter by saying, "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."

Rep. Tlaib also responded on Twitter, by saying, "He is the crisis. His dangerous ideology is the crisis. He needs to be impeached."

Rep. Pressley tweeted, "THIS is what racism looks like. WE are what democracy looks like. And we're not going anywhere. Except back to DC to fight for the families you marginalize and vilify everyday."

Rep. Ocasio-Cortez responded on Twitter with a thread that started with: "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."
