When Omar asked Dorsey during the call why Twitter didn't remove Trump's tweet, Dorsey told her Trump's tweet didn't violate the company's rules, sources told The Washington Post, which previously reported the conversation. Dorsey also pointed out that the tweet had been shared beyond the site but conceded that Twitter needed to do a better job of removing hate and harassing content from the site, the Post reported.

A Twitter spokesperson on Thursday confirmed the conversation between Dorsey and Omar, which occurred the same day that Dorsey and Trump had an Oval Office meeting.
