I am much more concerned with figuring out how to deal with the Russian meddling in our election than I am in reading the tea leaves as to whether Trump's attempts to influence the investigation rose to the level of obstruction of justice (but it was good to hear that Mueller is actively investigating that and he will follow that to conclusion...so despite his tweets Trump is not "vindicated" yet). And if Flynn or any other American (yeah, sure, John McCain, even Hilary Clinton) colluded or collaborated they should be charged and tried for any applicable crimes.
