Woah. There is another bombshell in the Flynn filing: there was a quid pro quo! This says Flynn’s lies to the FBI about his call w/ Kislyak was “MATERIAL into the nature of any LINKS or COORDINATION” b/w Russia and the “Trump campaign.” Here’s why this is big: 1/ 
What Mueller says here is that Flynn lying about the contents of the call - what he conveyed and how Russia responded - was relevant to the investigation into the CAMPAIGN’s links to Russia. Not the transition’s but the campaign’s. 2/
In other words, this means the contents of the call would seem to connect back to collusion during the election and the actions that took place during the campaign. 3/
This means what was concerning about the call was not some Logan Act violation or lying to Pence but the “underlying conduct” suggested on the call. And what Mueller is saying here is that “underlying conduct” revealed impt info about links b/w Russia and the Trump campaign. 4/
