Despite his argument that he was there to document the event as a journalist, Sullivan was a participant in the violent event, breaking through a barricade and entering the Capitol building while encouraging other protesters to do the same. It was his encouragement and active participation that led to his sentencing.
It’s important to note that Sullivan’s intentions and actions have been heavily debated, with some claiming he was an instigator while others say he was merely documenting the riot. Despite this, the court found him guilty based on the evidence presented during the trial.
