Publications are not always what they seem to be. The Nation has seemed to me to have had a history of excusing Soviet era evil and now that Russia is human rights disaster and oligarch factory, it still seems oddly ready to excuse it.
The much-loved and respected Paris Review for example had been CIA related and most readers did not have a clue.
From Wikipedia: (there re better sources)
" In 2007, an article published by The New York Times supported the claim that founding editor Matthiessen was in the CIA but stated that the magazine was used as a cover, rather than a collaborator, for his spying activities.[10] In a May 27, 2008 interview with Charlie Rose, Matthiessen stated that he "invented The Paris Review as cover" for his CIA activities.[11] Matthiessen maintained that the Review was not part of the Congress for Cultural Freedom (CCF), an organization used by the CIA to sponsor an array of literary magazines; but the record shows The Paris Review benefited financially from selling article reprints to CCF magazines."
George Plimpton, another founder, was a dreadful elitist and class conscious snob who looked down upon anyone without an Ivy League degree at a time when legacy admissions was at it height.
Matthiessen however, went on to mainly redeem himself and I have certainly benefited from reading his works.
