On April 23, Twitter CEO Jack Dorsey had a meeting in the Oval Office with President Donald Trump. According to an email message to Twitter employees from Vijaya Gadde, Twitter's global lead for legal, policy, and trust and safety, the purpose of the meeting was to discuss “the health of the public conversation on Twitter.”

In the email thread, first revealed by Motherboard, Dorsey himself explained, “As you know, I believe that conversation, not silence, bridges gaps and drives towards solutions." Dorsey pointed out that he had met "with every world leader who has extended an invitation to me, and I believe the discussions have been productive, and the outcomes meaningful.” While Dorsey noted that some employees might be less than thrilled with him taking the meeting, "In the end, I believe it’s important to meet heads of state in order to listen, share our principles and our ideas.”
