One thing about “hacking” —
If “the Russians” hacked Hillary’s email, it would have been no big deal — except for the fact that Hillary and the DNC were doing bad stuff and when the American voters found out the truth, it (may have) negatively affected the election.
You think the CIA has “pre-hacked” Trump’s secure phone? Well, I don’t expect him to do bad stuff, so I expect the damage from the CIA to be minimal.
I don’t expect him to do anything ‘bad’ either...but I do expect the CIA (which has practically declared war on him) to transcribe everything ever uttered on that phone.
