In a closed-door session, a frustrated Speaker Nancy Pelosi (D-Calif.) lashed out at about two dozen moderates and pressured them to get on board. “We are either a team or we’re not, and we have to make that decision,” Pelosi said, according to two people present but not authorized to discuss the remarks publicly.

But Ocasio-Cortez (D-N.Y.), the unquestioned media superstar of the freshman class, upped the ante, admonishing the moderates and indicating she would help liberal activists unseat them in the 2020 election.

Corbin Trent, a spokesman for Ocasio-Cortez, said she told her colleagues that Democrats who side with Republicans “are putting themselves on a list.”

“She said that when activists ask her why she had to vote for a gun safety bill that also further empowers an agency that forcibly injects kids with psychotropic drugs, they’re going to want a list of names and she’s going to give it to them,” Trent said, referring to U.S. Immigration and Customs Enforcement.
