This happened in 2021. Green was mad about the Green New Deal and AOC failing to "embrace our American ways." Sorry for the NYPost article, it was the one I found.

Rep. Marjorie Taylor Greene tore into Rep. Alexandria Ocasio-Cortez in a speech Saturday, calling the progressive Democrat a “communist” and criticizing the Green New Deal.
“She’s not an American. She really doesn’t embrace our American ways,” Greene said about Ocasio-Cortez, who was born in the Bronx, according to Fox News.
“You want to know why? She has something called the ‘Green New Deal,’” the Georgia Republican said about Ocasio-Cortez’s climate plan.
Last month Green called AOC a "pathetic little hypocrite" for her comments opposing the US attack on Iran.
Representative Marjorie Taylor Greene, a Georgia Republican, has called out Congresswoman Alexandria Ocasio-Cortez, a New York Democrat, for her criticism of President Donald Trump's attack on Iran.
Greene wrote on X, formerly Twitter, that Ocasio-Cortez, who had said Saturday's attack was "absolutely and clearly grounds for impeachment," was a "pathetic little hypocrite."
