Maybe there's a reason Donald Trump thought Jim Comey was a "nut job."
Initial reports about the Comey memo - the one that as of yet no one has actually seen - made it sound like Comey made the extraordinary decision to document a highly irregular conversation with the president.
But the more we learn about Comey in general, and about his attitude toward President Trump specifically, the more it sounds like Comey was rather paranoid about his relationship with Trump - both the perception of it and the reality.
