This and much more is the reason for the full court press to impeach President Trump. President Trump is peeling off the corruption in our government, hopefully getting to the core.
You are exactly correct. If they do not "take Trump out," Trump will take them out.
The Justice department at first was acting as a political hit squad against Trump. Today the Justice Department is fighting for the survival of the corrupt elite at their top and also the FBI which is part of the Justice Department.
