Insulting the Intelligence of the Congress

Congress was addressed by the state department.  It seems they insulted some republicans in the process.  Democrats do not concern Trump, but Republicans should.  If he insults too many of them, they will join in on some Democratic proposals.  They do not need many to get witnesses for his Impeachment trial.  I for one would love to see Bolton testify.  McConnell would fight that one tooth and nail.
