Here’s my tinfoil hat theory on this, as wacky as it may sound:
What if there is no human “leaker”?
What if someone in the Obama administration or Deep State really did install listening devices in the White House, and someone in the intelligence service is passing this info along to the press who are dutifully representing it as coming from “an unnamed source in the White House”?
/tinfoil hat off
Your guess is as good as any....
