I sighted a source one of many all reporting the same thing.
If you look at the article there are pictures of the Azov brigade in Washington being treated as VIPs by congress members and the Senate, the ban on the US supplying weapons to the AZOV brigade IS being lifted three years early and weapon supply is illegally happening anyway as part of the USA's cash dump in to Ukraine (as well as the one coming from the UK) The Azov "delegates were allowed to hold "charity auctions of their NAZI paraphernalia, and the official visit was allowed to go ahead without complaint while AZOV strictly speaking is STILL classed as a "Terrorist" organisation in the US.
I think who wrote the article is not important when the US government is evidentially openly colluding with an ultra right wing neo-Nazi organisation and treating them as heroes.
Personally I would be very worried.

Also there is precedent for the USA collaborating with Nazis when it was to their own benefit look up operation paperclip [en.wikipedia.org]

"The author you cite, Moss Robson, is an agent of OUN-B, a "Ukrainian Ultranationalist Organization", according to Google."
You are mistaken, I spent an hour researching this guy and he is a freelance Ukrainian journalist who writes and reports on "Stepan Bandera's internationally active Organization of Ukrainian Nationalists (OUN-B)" quote. Warning against them and their sub organisations, corrupting influence on youth and dangerously pro right wing extremism. He is certainly not a member or an agent
It was he who broke the story of the Azov visit to the USA. Only ONE MSM outlets reported on the visit and that was the Trumpist station NEWSMAX, who interviewed two members of the delagation Yulia Fedosiuk, Kateryna Prokopenko two active Azov members on air about the Russian detention of their husbands, both Azov fighters as POWs.

All the network news outlet studiously ignored the visit, failing to either condone or condemn it.
