Hillary lost despite getting support from Obama, Jay-Z, Beyonce, Hollywood, all of the LGBT community, the entire Democratic Party, the entire Mainstream Media, and 90% of the establishment.

In reality, Trump won with support from only 10% of the Republican Party and a bunch of Deplorables. 

Bottom line: The Establishment is so embarrassed by their defeat that they will say anything to save face, including that Trump got help from a vague number of Russian Hackers.
