“The idea itself is something that I am supportive of because taking an antitrust approach I believe is absolutely relevant and it’s appropriate to take,” the progressive House freshman said in an interview with Politico this week.

Warren’s proposal would break up companies like Facebook, Google and Amazon, targeting firms that both own an online platform and participate in its marketplace. Ocasio-Cortez echoed criticisms of such arrangements, arguing that in the case of Amazon, its role as “both the marketplace, producer, seller … creates an antitrust issue.”

The New York Democrat was an outspoken critic of Amazon’s plans to open a headquarters near her district in Queens, N.Y. And last month, she announced she had quit Facebook and called social media a “public health risk.”

This week, she leveled criticism at the social network’s business model.

“Facebook as a basic communications platform while also selling ads and also being a surveillance platform, I think those functions should be broken up, but how that gets levied and how that gets approached is what we need to take a fine-tooth comb at,” Ocasio-Cortez said.
