This story is from The National Review, a notorious purveyor of lies. None of the officials quoted mention "Antifa," a chimerical organization dear to Reich-winger's search for "others" to blame.
From Courthouse News Service:
"Feds arrest Navy reservist who blames Antifa for Capitol riot
Allegations of Antifa members infiltrating the crowd at the Capitol to instigate violence are not new.
An article by The Washington Times published on the day of the Capitol riot falsely claimed that XRVision, a software firm in New York, had corroborated speculation that two Antifa members “had infiltrated” the crowd of pro-Trump supporters who stormed the Capitol. The news outlet has since issued a correction retracting the claim."
But Blue you keep believing in your boogeymen if it helps you stay angry. It's been said that "Every true Publican needs an "enemy of the state" to keep their juices flowing with rage."
