He has said he will not resign his position, writing on X: “I’m staying. I’m all in.”

The Washington Post reports that “at least” five members of an antisemitism taskforce at the organization have resigned in protest. One staffer in the internal meeting called the issue her “final straw”.

Roberts previously called those speaking out against Carlson a “venomous coalition”, a loaded phrase he subsequently said was a “terrible choice of words” that caused “justified concern” among those who worry about rising antisemitism.
