It's now generally accepted, if not 100% proven, that the Trump Tower meeting between Trump campaign officials and a mysterious Russian woman was set up by Fusion GPS. Among other evidence, the woman met with Fusion GPS both before and after the meeting. And, of course, Fusion GPS was working with the Hillary campaign and Christopher Steele to convince the FBI to investigate the Trump campaign for Russian collusion that did not exist.
As far as I know, this is new information, and it would be devastating to the FBI's narrative if they were directing Sater to encourage deals with the Russians while they were trying to investigate the Trump campaign for Russian connections. And, yes, the Russian building angle has been used in various Democrat attempts to smear Trump, most particularly with respect to Cohen's congressional testimony.
And, conveniently, Sater was mentioned in the Mueller report several times but not his status as an informant. That's not necessarily surprising (it's reasonable to put a high priority on protecting the names of sources) but when those sources are being used to entrap innocent people and conduct a political coup, the public interest outweighs the secrecy.
Not mentioned: there is serious and signifcant doubt as to whether the charges in this case could possibly be campaign finance violations. Cohen basically pled to legal conduct as part of a "get Trump" effort. When Edwards was charged with similar but significantly worse conduct -- he paid off his mistress with campaign funds from a donor -- he was acquitted. Even those charges were considered controversial and a bit of a stretch.
The leaker here is basically saying Trump wasn't charged because he is the President. But that's pretty much never stopped anyone from enforcing campaign finance law before, and there are lots of other reasons not to prosecute a case like this.
Leaking this information is almost certainly a violation of DOJ ethics rules for prosecutors. As a prosecutor, you either indict, or shut up. You don't leak smears.
BOMBSHELL: Mifsud prepared to testify to setup operation
So here's the deal. Mifsud -- a man with extensive ties to Western intelligence agencies and politicians with documented photographic evidence -- says he was tasked with meeting Papadopoulos and feeling him information on Russian dirt about Hillary. Mifsud then says he was tasked with introducing Papadopoulos to Russians. Again, tasked. Later, Papadopoulos talks with Downer and mentions Russian dirt on Hillary. (No emails mentioned either time -- all three parties agree on this).
It seems certain now that this whole operation was a setup designed to give the FBI a deniable reason to get an investigation opened into the Trump campaign. And the deception continued past the election, past the inauguration, all the way into the Mueller report, which describes Mifsud as a Russian agent.
So who tasked Mifsud with setting up Papadopoulos? Let's follow that up the chain.
