> Members of this group were arrested and convicted in a plot to attack the inauguration ball using acid in the ventilation system and other alleged tactics.

That's incorrect. Convicted liar and video troll James O'Keefe did get them on video talking about acid, but they never acted on the plan, never attempted to acquire acid. The prosecutors were only able to get the defendants to take a plea deal for a "conspiracy" misdeameanor with no criminal conviction or record.
