Trump / election team, got caught up talking to Russians with a strong interest in bringing down the US. US security monitors foreign agents of countries unfriendly to them. If a Presidential candidate or his election team is stupid enough to get caught dealing with the enemy , that is not Security forces fault!!
Those agents were NOT monitoring US citizens but foreign agents who just happened to be talking to Americans and not just ordinary Americans but to a Presidential candidate's team.
Oh and wikileaks comes from Russia these days as it was the only country that was willing to take in the guy who hacked the US government files. If it is okay to hack into and release secret government files, why get all upset when the agency charged with security catches traitors legally.
Certainly that is the speculation put forth by some. I haven't seen or heard any completely reliable unpartisan evidence yet that would indicate this to be a fact. Certainly will monitor should that evidence come forth.
As for WikiLeaks, they just released the Dems own e-mails (not the us government files) so it seems like the Dems kind of did it to themselves.
