“Likely” it was the Russians. But there is a very strong incentive for the Mossal and the Netanyahu government of Israel to keep surveillance on the Democrats, who are apparently intent on betraying the nation of Israel to ISIS. These Democrat party people are not to be trusted, even in trifling things.
They don’t have projects, they have schemes. They form no government, they form regimes.
The FBI, for the moment, is like a guard dog kept tethered closely with a taser shock being delivered every few minutes. The Current Occupant has no trust of them either.
Please see my post #26 for similar thoughts regarding Israel.
Also, agree with your second point about schemes. They don’t want to govern; they want to RULE.
