Special Counsel Robert Mueller's court filing on Michael Flynn provides plenty of intrigue, not the least of which concerns what cases are out there that might ensnare President Donald Trump.
"It's clear that there are three matters that Flynn is getting credit for helping with," former White House ethics counsel Norman Eisen tells me.
"One is collusion; no surprise there because of the contacts with Russia that he lied about. The other two were blacked out in the memo, but the second is likely the Special Counsel's other main focus: obstruction."
He explains: "Remember, it was Trump's request to [then-FBI Director James] Comey to 'see his way clear' to letting Flynn go, that triggered the obstruction investigation. Flynn may well have a great deal to say about why Trump was so desperate and much more about the elements of obstruction." A useful analysis can be found in a report by Eisen, Barry H. Berke and Noah Bookbinder for the Brookings Institution.
But what about a third case, one that seems not to be under Mueller's jurisdiction? Eisen says that one's a "mystery." He speculates that this might point to the Stormy Daniels campaign-finance case in the Southern District of New York, although we have seen "no previous indication of Flynn's involvement in that".
