President Trump hosted tech leaders at the White House, including Apple CEO Tim Cook, Microsoft CEO Satya Nadella, and Amazon CEO Jeff Bezos.

The White House has yet to announce which companies or individuals are participating in the social media summit, but The Washington Post reported on July 2 that a handful of conservative critics have been invited: Charlie Kirk of Turning Point USA, and PragerU - a non-profit organization that produces YouTube videos with a conservative perspective.

Twitter representatives declined to comment on the report; Facebook and The White House didn't respond to a request for comment as of publishing.
