Sure, it is, and it's also necessary for active personnel at that clearance to be able to seek their wisdom and counsel.
It's hilarious seeing all the cucks turn out for Trump on this issue. No, this private sector clearance has
never been a problem, and nobody has ever questioned John Brennan...until this President; a man who surrounded himself with secret foreign agents, whose lawyer is a felon, whose campaign manager is a felon, who fucked a degenerate stripper while his wife was pregnant (and continues to try to lie about it), who has been caught in more verifiable lies than any politician in American history, who settled his own felony fraud case (defrauding his own biggest fans) for $25m before inauguration, who has scammed innumerable modest investors in real estate projects, who has repeatedly promised money to charities that he never pays, who has illegally used that charity to pay off successful litigation against him, who has lied and lied again to the American people's faces about his dealings with Russian government officials including Russian counterintelligence operatives, and who is currently shitting on
his own appointment to head the Department of Justice in the same fashion he has attempted to vilify Brennan.
What sort of Benedict Arnold scumbag does one have to be to back Trump over the 175 former officials--
of both parties-- who signed that letter?
175 former US officials added to list denouncing Trump for revoking Brennan's security clearance
