So that's why he's peevish

Trump's feeling under siege with the Sessions controversy.  Can't say that I feel for him.  He's a particular kind of crazy that's going to dig a hole for himself from which only ever bigger lies can rescue him.  

He's got an interesting problem now:  He's president.  It's not (currently at least) the Kingly role he imagined.  He's got duties, and responsibilities, and massive spotlights on his (and his staff's) every move.  320million+ people are counting on him to "Do The Right Thing".

Unfortunately, that's not Trump's style.  He tells ever bigger lies, says things that are ever more incendiary, and generally tries to hide his failings with chaos and deceit.
