Abolish the FIB. It is hopelessly corrupt and its disbandment would serve as a very useful object lesson to the rest of the Deep State - and anybody else - that there will be consequences for becoming nothing more than the STASI of the Democrat Party.
Then after its disbandment, prosecute the bad actors for their crimes....and not in the DC Swamp where the Swamp courts cannot be trusted due to their corruption.
Where is Vlad the Impaler when he is needed?
