Mr. Biggs’ activities that day were extensively recorded by himself and others. His walk from the Washington Monument was filmed by Eddie Block, a proud boy on a scooter who rolled behind him and identified Mr. Biggs and others in his commentary. Mr. Biggs appeared repeatedly in photographs and recorded himself climbing the Capitol steps.

It was a long, awkward road that got him to this point. Mr. Biggs, 37, also known as Rambo, was a Florida DJ who “romped around nightclubs pounding ecstasy” before joining the military in 2007, he said on his broadcasts. He was posted to Iraq for a year and then to Afghanistan. He made his news media debut after leaving active service in 2012.

In 2008, Michael Hastings, a reporter embedded with Mr. Biggs’ unit in Afghanistan, encouraged him to appear on camera in the news media upon his return to the United States, Mr. Biggs said. Before Mr. Hastings died in a car accident in 2013, Mr. Hastings wrote a profile of General Stanley McChrystal for Rolling Stone, which ended the general’s military career.

Mr. Biggs ‘hiatus came after fueling conspiracy theories about Mr. Hastings’ death. Mr. Jones invited him to Infowars, the far-right, conspiratorial radio and online show.

Mr. Biggs joined Infowars in 2014 and traveled the next year to attend racial justice demonstrations in Ferguson, Missouri, and to the 2016 occupation of Malheur Wildlife Refuge in Oregon by armed right-wing extremists. Escorting Mr. Jones to Republican 2016. At the National Convention, Mr. Biggs fell in a dispute with communist protesters, including one who burned an American flag.

He and another Infowars employee claimed they were burned to put out the fire. In a mundane video called “Joe ‘Rambo’ Biggs: Commie Crushing Crusader!” Mr. Biggs said he “jumped” over the “cops”, tore off the protester’s shirt and gave him a “stomp”.

Police charged protester Gregory “Joey” Johnson of the offense.

When Mr. Johnson’s attorneys saw the videos of Mr. Biggs’s allegations, they demanded that the charges against Mr. Johnson be dropped, which they were. Mr Johnson sued the City of Cleveland and its police force on the grounds that they violated his First Amendment rights. He received a severance payment of $ 225,000.
