Is Stefan Halper the classified informant that Devin Nunes is getting stonewalled by DOJ as a classified intelligence "source" who must be protected? And POTUS may have signed an EO to release the details to Congress on whether this guy was working for the DOJ/FBI.
Halper may have been an FBI spy to "entrap" George Papadopoulos into Russia collusion, kicking off the FBI counterintellegence investigation (i.e. the "insurance policy") and FISA abuse scandal.
If you dig into Halper this guy has a shady past with deep ties into the C_A, MI6, DOJ, FBI.
