“foreign intelligence value” has no legal definition and is left solely to the judgement of those empowered to unmask.
Only 3 people have the power to unmask, Loretta Lynch, John Brennan and Susan Rice.
Calling John Brennan to the witness stand. Sir, was there legal justification (national security) to unmask Trump and his associates and if so, why did you not request that it be done?
Calling James Clapper to the witness stand. Sir, was there legal justification (national security) to unmask Trump and his associates and if so, why did you not request that it be done?
Have you seen the FISA court approved rules concerning unmasking?
