Acquiring donations or other items of value for an election, obstruction, and anything else discovered.

You seem to be forgetting that Bill Clinton wasn't being investigated for his adultery when the Monica Lewinsky situation arose.

Besides.....how many other presidents have you heard of discussing pardons just for the heck of it?

I won't say that there is for sure anything to the investigations, but 1) it is the Trump administration's fault that all of this is taking place with their lies and omissions (of course, I'm sure you're a fan of the GOP mantra "responsibility for thee, but not for me"), and 2) you seem to be adamant that there is no way that a guy, with a history of stiffing people, adultery, admitted sexual assault, and bankruptcies, could have possibly done anything wrong.
