Should Congress Stop Messing With Rod Rosenstein?

Republicans in Congress have made it no secret of the fact that they want to end the Russia investigation.
One way of doing that is by putting pressure on Rod Rosenstein.
Republicans claim that pressure on Rosenstein is just "oversight."
According to Politico, Republicans are trying to force Rosentein to resign by discrediting him.
They're also forcing him to comply with unconventional requests.
The biggest bone of contention for the GOP are documents Rosenstein has for his investigation.
