By Josh FeldmanJul 9th, 2021, 9:15 pm MSNBC’s Chris Hayes opened his show Friday night going off on the anti-vaccine propaganda spreading on the right, and he again called out hosts on Fox News. Hayes asked Media Matters President & CEO Angelo Carusone about the “just-asking-questions trollingly, you know, opposition to any pro-vaccine moves.” Carusone in particular pointed to the incredibly irresponsible commentary from Tucker Carlsonspeculating about people dying after getting the covid-19 vaccine. “A very, very minor conspiracy theory that was circulating online in the fever swamps,” Carusone said. “And he plucked it out of there and gave it a lot of push and that was really when things started to shift over at Fox News.”
