The core of the article is this exchange between AOC and former Trump lawyer Michael Cohen at his hearing before the oversight committee, which started off the fraud investigation:

Ocasio-Cortez: To your knowledge, did the president ever provide inflated assets to an insurance company?

Cohen: Yes.

Ocasio-Cortez: Who else knows that the president did this?

Cohen: Allen Weisselberg, Ron Lieberman and Matthew Calamari.

Ocasio-Cortez: And where would the committee find more information on this? Do you think we need to review his financial statements and his tax returns in order to compare them?

Cohen: Yes, and you would find it at the Trump Org.

Definitely give the whole thing a read, though.
