The arrested 48-year-old Nathan Entrekin filmed his movements around the Capitol in a gladiator's costume on a mobile phone - he was recording a video for his mother.
In the video, he noted that he portrays Captain Moroni from the Book of Mormon defending his people against those who intended to overthrow democracy and bring their king to power.
As of June 10, the number of those arrested during the storming of the Capitol has almost reached 500 people.
