Incredible new stuff on Sater from Josh Marshall
"It seems highly likely that Sater has deep and longstanding ties to at least certain elements of US law enforcement and intelligence. It's clear he worked on their behalf in some capacity and seems quite likely, though not certain, that he aided the US in purchasing black market weapons in Russia and/or Central Asia as a way to skate on his fraud conviction. One could definitely argue that his work in that role - basically being a US operative, in some sense - runs counter to any theory that Sater is some agent of the Russian government or in any way a conduit for Russia capital or advancing Russian interests with Trump. But Sater clearly has many masters or rather works with a bewildering cast of characters in the interests of saving his own neck. So anything is possible. If nothing else, the CIA/arms smuggling story, if true, would suggest he was quite plugged in with the Russian and post-Soviet criminal underworld. So there are many possibilities."
