IT'S A BIG THING! Putin is an autocrat who rules a foreign state, with an increasingly hostile posture towards the United States and a substantial stockpile of nuclear weapons. The stakes involved in finding out 'what's going on' as Trump might put it are quite a bit higher. Trump's financial empire is heavily leveraged and has a deep reliance on capital infusions from oligarchs and other sources of wealth aligned with Putin. That's simply not something that can be waved off or ignored.
