QAnon[a] (/kjuːəˈnɒn/) is a far-right conspiracy theory detailing a supposed secret plot by an alleged "deep state" against U. S. President Donald Trump and his supporters. The theory began with an October 2017 post on the anonymous imageboard 4chan by someone using the tripcode Q, a presumably American individual that may have later grown to include multiple people, claiming to have access to classified information involving the Trump administration and its opponents in the United States. Q has falsely accused numerous liberal Hollywood actors, Democratic politicians, and high-ranking officials of engaging in an international child sex trafficking ring and has claimed that Donald Trump feigned collusion with Russians in order to enlist Robert Mueller to join him in exposing the ring and preventing a coup d'état by Barack Obama, Hillary Clinton, and George Soros. "Q" is a reference to the top-secret Q clearance. QAnon believers commonly tag their social media posts with the hashtag #WWG1WGA, signifying the motto "where we go one, we go all. "
