Actually, it's nothing more than lazy slander pepetuated by duopoly apologists.

There's zero proof Stein is "Putin backed". She once sat at the same table at an international conference and barely spoke to the man. That's it.

Meanwhile, AOC has been publicly performing as a genuine progressive for her voters and constituents all while voting and acting like a corporate Democrat behind the scenes.

This was debunked back when it came up in 2017 (?) There's a good article about it here. The summary is that Stein was there in a diplomatic role. You know, as presidential candidates do. The Senate Intelligence Committee investigated her and found no wrongdoing.

A campaign spokesperson told Newsweek that Stein "attended at her own expense to spread a message of peace and diplomacy" and gave a speech in Moscow "in which she criticized the excessive militarism of both Vladimir Putin and U.S. leaders."

Speaking to The Intercept in 2017, she said the notion that it was an "intimate roundtable" was "mythology," and that Putin and his associates "weren't at the table for very long." Stein said that "nobody introduced anybody to anybody" and that she "didn't hear any words exchanged between English speakers and Russians" due to the lack of a translator.

Stein said that Putin had appeared to make a speech and left immediately after. "Nobody cared to make introductions. This wasn't intended to be a discussion of any sort," she told the outlet.
