This twitter-based scandal has gotten hilariously ridiculous.
Fans of Trump, fans of Pelosi, and even detractors of AOC have now been put in very awkward positions.

First of all you had Trump jumping to Pelosi's defense.

“When will the Radical Left Congresswomen apologize to our Country, the people of Israel and even to the Office of the President, for the foul language they have used, and the terrible things they have said,” Trump wrote Monday morning on Twitter. “So many people are angry at them & their horrible & disgusting actions!”

In a second tweet less than an hour later, Trump warned: "If Democrats want to unite around the foul language & racist hatred spewed from the mouths and actions of these very unpopular & unrepresentative Congresswomen, it will be interesting to see how it plays out. I can tell you that they have made Israel feel abandoned by the U.S."

We need to pause on this for a moment.
Trump called Pelosi a “nasty, vindictive, horrible person" just a few months ago.
From a partisan viewpoint, Trump should be delighted with the spat.
So why would he care about AOC hurting Pelosi's feelings if he didn't recognize that Pelosi is part of the establishment like Trump is?
Then Trump takes it too far.

The posts represent the president’s latest broadside against Reps. Alexandria Ocasio-Cortez (D-N.Y.), Ilhan Omar (D-Minn.), Ayanna Pressley (D-Mass.) and Rashida Tlaib (D-Mich.), the women of color whom Trump tweeted Sunday morning should "go back and help fix the totally broken and crime infested places from which they came."

Trump also wrote that the four congresswomen "originally came from countries whose governments are a complete and total catastrophe," even though three of the lawmakers were born in the United States. “These places need your help badly, you can’t leave fast enough. I’m sure that Nancy Pelosi would be very happy to quickly work out free travel arrangements,” Trump tweeted.

Ocasio-Cortez was born in the Bronx borough of New York City, Pressley was born in Cincinnati and Tlaib was born in Detroit. Omar, a Somalian refugee, immigrated to the U.S. with her family in the early 1990s, and became a citizen in 2000 when she was 17 years old.

Trump, addressing reporters outside the White House on Monday afternoon, said his tweets were "not at all racist," and doubled down on his line of attack against the congresswomen.

"If somebody has a problem with our country, if somebody doesn't want to be in our country, they should leave," the president said.

So they should "go back" to New York City, Cincinnati, and Detroit?
Too late. They already have. Obviously this comes from a viewpoint of who "looks American".
Even fellow Republicans have stayed silent.
And then the "Love it or leave it" line is a topper.

So now Pelosi has found herself forced to defend the same congresswomen that she was trying to slap down just a few days ago, while at the same time condemning the President who is defending her.

The president, asked by reporters at the White House whether he was concerned that white nationalists are backing his remarks, said, “It doesn’t concern me because many people agree with me.”

Pelosi said the House resolution will be offered by a group of Democrats who were born abroad, and she called for Democrats and Republicans alike to support it.

“I reject the president’s xenophobic comments meant to divide our nation,” Pelosi said in a letter to colleagues.

Just on the surface this is comedy gold.
On a deeper level, this feud makes it more difficult to rationalize the line that AOC is just an establishment tool (unless you believe in 11th dimensional chess).
It looks a lot more like a power struggle in the Democratic Party, and the presidential man-child butted-in and exposed this game for what it is.

What is interesting is that "the Squad", just four freshmen in Congress, who didn't get bribed on their way into office, can cause so much disruption.

It tells me two things are likely true:
1) TPTB cannot tolerate any dissent of any kind, and
2) TPTB's control is very fragile (see #1)
