As part of his bid to encourage Fox News viewers to question the safety of COVID-19 vaccines, Tucker Carlson in June praised the work of an obscure campaign group named the Informed Action Consent Network, or ICAN.
Carlson described ICAN as "a group that advocates for transparency on vaccines," citing emails it had obtained to attack White House medical chief Dr. Anthony Fauci, a popular hate figure for the far right.
ICAN is seen by many as a more extreme — and dangerous — organization that Carlson's description let on.
It was one of the figures on the so-called "disinformation dozen" list cited by President Joe Biden's administration as the main sources for anti-vaccination disinformation online, which Biden has called on Big Tech to combat.
ICAN is particularly notable, experts say, because it has actively courted conservatives and supporters of former President Donald Trump, whom multiple studies have shown to be the most reluctant to trust the shot.
Since being founded three years ago, the group has waged a media, legal, and online campaign to hammer home the theory that the damage caused by vaccines is being systematically suppressed.
The group is based in Texas, a hub for libertarian right-wing causes, and the campaign is — per a Washington Post investigation — largely bankrolled by the New York financier Bernard Selz and his wife, Lisa.
