Not sure it's in dispute that Donald could've fired Comey for any legitimate reason (or for no reason at all), but I'm surprised Dershowitz is taking a position, counter to nearly every other position that I've seen out there from attorneys that Donald, can fire Comey for an illegal reason. Dershowitz toeing the "it's not illegal when the president does it" line. Sad !
And yes, as RSF points out, one would hope if an independent special counsel concluded that obstruction of justice had occurred that even the spineless GOP Congress would initiate impeachment proceedings, even if the president can't (read: won't) be indicted while in office.
