Actually even the New York Times, Washington Post, CNN, etc have admitted that the Russian hoax was made up by Hillary Clinton's campaign.The people that are investigating Trump are the people that uncovered the Russian Hoax, not started. There has been solid evidence found that there was Russian interference with the 2016 elections that helped get Trump elected.
There was no Russian Hoax to be made, because as I said, evidence has been found to prove that it existed. Please do your research.
