Yes I can see the political games. In fact Trump may have leaked he was angry with Sessions as a head fake, who knows. The hearings usually produce some surprises, good, bad, or both.
The press misinterprets and stretches everything about Trump. It is gaslighting the public, full on. Any Trump frustration is taken as literally against somebody. Notice Comey "surprise" at being fired, after all, Trump had told him he wanted him to stay. I point the Comey relationship as an example of misdirection going the other way.
I speculate the recent "Comey is considering firing Mueller" stories, citing Chris Ruddy, is rooted in the likely true notion that Trump was "gaming out the consequences" of various courses of action. Consider all courses (or many) in a decision matrix, pros and cons of each course. "Fire Mueller" would be one of the possibilities, and it probably ranks dead last of all the options. That gets converted to "Trump is considering firing Mueller."
