Senator Graham remembers that the government was set up to be a check and balance against abuse of Power.

Senator Graham came out against the firing of Jeff Sessions today
Senator Sasse and Senator Grassley reportedly also came out against the idea.
I wish my Senator James Lankford (forget the useless snowball Senator Inhoffe he cant get his head out of the sand) would do the same.
Additionally Graham says he will introduce legislation (I'm sure Trump will veto it) to protect special prosecutors in the future.  Good news for America, at least a few GOP members are stepping up to their responsibility.
