Greenblatt wrote that “Carlson’s embrace and amplification of white supremacist talking points galvanizes extremists and mobilizes their movements. We know this because we have been at the forefront of tracking extremism for decades.”

The letter told Murdoch that ”you are giving license to yet another conspiracy theory: that January 6th was an inside job with the intention of rounding up and imprisoning conservatives.”

Greenblatt continued, “As the head of a well-established news organization, I have to ask: where is the line for you and Fox? How many more people need to die or how many individuals must subscribe to groundless conspiracies before you say enough is enough? Inflammatory rhetoric of this sort is neither legitimate political discourse nor spirited debate. It is dangerous rhetoric that could catalyze violence, whether directed at the Jewish community or other minority groups.”

The letter closed by asking Murdoch not to air the series.
