Re: Responsible observation
Speaking of Responsible observations:
I have responsibly observed that, every time there's a bit a news that paint a negative or suspicious light on Trump, the Trump campaign, Trump campaign associates and their suspected connections to the Russian Government, or Russian Intelligence Services, there is a not insignificant number of very eager Anonymous Cowards who take it upon themselves to muddy the waters with blatant whatabout-ism efforts.
Just a Responsible Observation.
Insofar as why NSA was listening on Sergey Kislyak's phone, and why it intercepted communications between Kislyak and Michael T. Flynn: because that's why NSA was invented in the first place. That's their job.
