I can't speak on individual journalists here, but connections, no matter how loose, to Russia Today (RT) and Iranian news is nothing new. There is, undoubtedly, a connection to the respective governments. I don't think we can deny it outright and it's at least partially true - this is something I keep in mind any time I read a news source with a similar background, and I supply those articles with additional information anywhere else I can obtain it.
As far as what to make of it? Of course they have to add in extraneous bullshit, that goes along with our (the US') support for Ukraine and Israel at such uncertain times.
It'd be a shame to lose a site that does, at least occasionally, bring out excellence in journalism that can be hard to find (except 30+ years into the future when The New York Times decides it's acceptable, or when the CIA claims it is no longer a National Security threat to release).
We should still seriously examine such claims and bat a critical eye to the underlying bias, is what I'm saying. Some of these same outlets and foreign governments would, for example, gladly accept people like Jackson Hinkle to speak up and we certainly don't have to give any credit where it's not due... let's just say the US and UK left some dirty international connections in the USSR and Middle East that were left unattended post-Soviet collapse and they have some interesting ideas about how to use left-wing groups for a certain agenda. Now that blowback is slowly settling in, the US isn't so proud her old friends from the good days.
Keep reading, but always read a little more.
