Republican Rep. Marjorie Taylor Greene confronted Democratic Rep.
It prompted a complaint by Ocasio-Cortez's to authorities to ensure Congress remained 'a safe, civil place for all members and staff'.
The Epoch Times reached out to Ocasio-Cortez's office for comment.
The Georgia congresswoman, known as MTG, then reportedly raised her voice to accuse Ms Ocasio-Cortez of supporting antifa, a loosely knit group of far-left activists, and Black Lives Matter, which Mrs Greene reportedly branded "terrorist" groups.
Rep. Ocasio-Cortez wisely chose not to engage with Greene, "only turning around once and throwing her hands in the air in an exasperated motion". "You are also a hate-America terrorist sympathizer". "Why do you support terrorists and antifa?"
Ocasio-Cortez has been critical of Israel over its ongoing military assault in the Gaza Strip, saying Palestinian human rights have been violated, but she has also called Hamas's rocket attacks "condemnable".
'We hope leadership and the Sergeant at Arms will take real steps to make Congress a safe, civil place for all members and staff - especially as many offices are discussing reopening. "One Member has already been forced to relocate her office due to Congresswoman Greene's attacks".
According to The Hill, Greene in turn said that "there was no screaming", and added that the House Ethics Committee should look into AOC for suggesting that previous Trump staffers should be punished for their affiliation with the previous administration.
"This is beneath the dignity of a person serving in the Congress of the United States", Pelosi said, noting that the incident has been reported to her and referred to the Ethics Committee.

"She's a chicken, she doesn't want to debate the Green New Deal", she said to a small group of reporters and onlookers near the entrance to the chamber.
'They need to defend their legislation to the people.
Senate Minority Leader Mitch McConnell (R-Kentucky) denounced Greene's embrace of QAnon conspiracy theories and "loony lies" as a "cancer for the Republican Party".
She accused President Joe Biden of issuing a "blanket statement" that failed to acknowledge the root causes of the crisis which included the Israeli police raid of the Al-Aqsa mosque and the looming evictions of dozens of Palestinians from their homes in East Jerusalem.
Greene described how she approached AOC to reporters, "By talking to her, talking to her". It takes a side - the side of occupation'.
That member who moved offices is Missouri's Cori Bush, who said earlier this year that a maskless Greene stopped her in a hallway and "berated" her.
