Should the FBI be defunded?

No.  It's time to arrest the top DOJ and FBI officials and try them for treason.   Of course it will not ever happen.  We're on a fast track to 3rd country communism at the behest of the Democrat Party and its deep state cohorts in step with the national media.  Democrats will never allow Trump to ever serve in any public office.  They will pull out every trick in their play book, and some new creative ones, to keep Trump at bay where he belongs.  In the final analysis it may take armed insurrection to root out the communist pigs lurking under the cloak of  government.  I'm a WW II Veteran.  I saw one of my fellow comrades interviewed on TV and tearfully said, "This is not the country we fought for".  I shed tears with him.
