The Atlantic has fired conservative columnist Kevin Williamson, who tweeted that women who have abortions should be hanged.

“Late yesterday afternoon, information came to our attention that has caused us to reconsider this relationship,” Atlantic editor-in-chief Goldberg wrote in a memo to employees on Thursday. “Specifically, the subject of one of Kevin’s most controversial tweets was also a centerpiece of a podcast discussion in which Kevin explained his views on the subject of the death penalty and abortion.”

He added: “The language he used in this podcast—and in my conversations with him in recent days—made it clear that the original tweet did, in fact, represent his carefully considered views.”

Goldberg had previously responded to the backlash over Williams’ hiring by defending his decision, saying that “I don’t think that taking a person’s worst tweets, or assertions, in isolation is the best journalistic practice.”

On Wednesday, MediaMatters resurfaced a National Review podcast from 2014 in which Williamson said he “would totally go with treating [abortion] like any other crime, up to and including hanging,” and repeated the sentiment several times throughout.
