Among the attendees of President Trump’s rally in Florida were people holding up signs promoting an online right-wing conspiracy persona – who’s been targeting movie stars and the Democratic Party alike.

The signs “We are Q” and “Q” appeared near the front of the crowd during Trump’s speech in Tampa, as many live-streams showed.

It was an apparent reference to QAnon, a group that originated on the 4chan messaging board around an anonymous user, “Q,” who claims to be a member of the US military intelligence.

People wearing QAnon shirts and flashing similar signs were also pictured while lining up for the rally.
