Waleed Shahid wants a war within the party.

[George II]

53. The headline of the article is a direct quote by Waleed Shahid. He was spokesperson for JD in 2019..

....when the article was written and he still is. The main focus of the article is him and Justice Democrats.

In 2019 Chakrabarti was Ocasio-Cortez' Chief of Staff. He resigned later that year.
In 2019 Ocasio-Cortez was representative for NY-14. She still is.

The two people that I now know you were talking about (although not the main focus of the article) are those two. It's not true that they're not in the position now that they were back in 2019. Yes, One resigned although stayed very active with all involved, the other is still at the same position.

It's irrelevant how many times people are mentioned, the article is about Waleed Shahid and Justice Democrats.

The initial point of the discussion is that Justice Democrats has all but declared war on the Democratic Party. That was the case in 2019 at the time of the article (indeed, in 2017 when they first announced their intentions), it was true in 2020, and is still true in 2021.

Just a casual review of both Waleed Shahid's and Saikat Chakrabarti's recent tweets show that's the case.
