They are keeping the Russia investigation out of the news as not to taint evidence.
Remember, there were closed hearings with Comey, Sessions and others where the public has no idea what was said.
It may take some time to pull it all together. And maybe nothing will formally be pursued.
But the investigation is certainly happening.
Its is Trump telling us that Obama knew more than he told us.
It was also Trump that said stories that there were any Russian meddling was fake news.
So Trump is contradicting himself again.
Obama didn't want the appearance of interfering in the election in Hillary's favor so he had to tread lightly as the Russia news came in.
The Russian interference was certainly made public before the election.
Trump even publicly told Russia to hack Hillary's emails. Remember that?
