Now that James Comey has testified that he told Rod Rosenstein about his concerns about Trump's conduct, after Rosenstein was sworn in and not long before Rosenstein wrote the letter Trump used as his excuse to fire Comey, the Department of Justice ethics office must open a serious investigation of Rosenstein because everything about his behavior as Deputy Attorney General has stunk like a rotten skunk whose carcass had been shoved to the side of the the road.  That rotten skunk would be Rosenstein's reputation as a straight arrow.  He's as bent as any of his more infamous predecessors.
