The rightwing media ecosystem spins up narratives to serve their agendas after tragic events, regardless of accuracy

Tina Smith, a Minnesota senator confronted Mike Lee, a Utah senator, on Monday to tell him directly that his social media posts fueled ongoing misinformation about a shooting that killed her friend.

Lee’s posts, which advanced conspiracies that a Minnesota assassin was a “Marxist” and blamed the state’s governor for Melissa Hortman’s death, were among many threads of false or speculative claims swirling online after the killings.

Smith told Lee his posts were “brutal and cruel,” according to CNN. “He should think about the implications of what he’s saying and doing. It just further fuels this hatred and misinformation,” she said. She wanted him to hear from her directly how painful it was to see his words after the brutality her state endured. Lee didn’t say much, according to Smith, and seemed surprised to be confronted.

Within hours of the shootings, rightwing social media accounts with millions of followers manufactured false conspiracy theories about the suspect and his motives, falsely portraying the man whose friends say he is an evangelical Christian Trump supporter as a radical leftwing assassin and attempting to paint him as a political ally of Tim Walz, the Democratic governor and former vice-presidential candidate.
