Dem Rep. Lieu: Russia Indictments’ Timing a ‘Poke in the Eye’ to Trump

Of course.  Rosenstein should be impeached,  if for no other reason than for his attempt to subvert Trump's summit with Putin.  I am not going to spend much time on his announcement,  just to remind you of the obvious:  Rosenstein hates Trump and his bias drove him to . . . . 
make the announcements of Friday.  

No one needed to know about the indictments  before Trump's summit with Putin.   Why did Rosenstein pretend that these 12 indictments would ever be served?  I mean,  all live in Russia.  None of these Russians are coming to America to be harassed by this pinhead calling himself an  Associate Attorney General.  The announcement was intended to undermine the President,  and members of Rosenstein's own Party could see through the facade.   Someone should take this skinny nothing of a man behind the woodshed,  and teach him a lesson that he will not soon forget. 

And,  please don't remind me that Rosenstein is a Republican.  He is no more a Republican than a cow is a cat.

Update :   Turns out all info released by Rosenstein was made public back in April,  so do not tell me that his intentions were honorable.
