So simple they lied about them for months. And even the conclusion of the few agencies was not based on actually examining the server themselves because the DNC refused to turn it over.
Via Daily Caller:
The New York Times said the facts behind a bogus Russia claim the media has been pushing for nine months now are “simple” in a story Thursday that does not mention the paper rated the claim as true when it was first used by Hillary Clinton.
Trump put the paper of record in a tough spot Thursday when he drew attention to the fact that the press has confessed to pushing a false claim that “17 intelligence agencies agree” on Russian interference in the presidential election. The New York Times and Associated Press both acknowledged the Clinton talking point is false this week, and conceded that in fact only three agencies working under the aegis of the Director of National Intelligence weighed in on the election meddling.
