Regular readers of this blog know I'm no fan of Donald Trump His critics have been pronouncing him guilty of obstruction for days. His defenders have been doing what they always do - blaming everyone else. If I were making the call, I'd nix any plan to prosecute him, at least for the moment.
I'd recommend the Sidebars blog for a perspective on exactly what is needed to prove obstruction from a former federal prosecutor. The most difficult element is proving a corrupt intent. Based on the evidence that's out there, together with Trump's denial that he asked anything of Comey, this is a loser.
Personally, I believe Comey. But would 12 people be convinced beyond a reasonable doubt? That's unlikely.
