"There's no evidence"its funny really...Trump claimed the Iowa and Wisconsin primaries were rigged when he lost them, he claimed the 2016 election was rigged but he actually won it, he claimed the federal courts were rigged when he had to settle the Trump U deal, he claimed the Emmys were rigged when he didn't win one...its kind of a pattern actually
It's a favorite Obama line. A line used heavily during the Russian Illusion when information came out that the FBI was in cahoots with the White House.
The fact is that there's no evidence at this point that the election was conducted fairly. How could Trump be up by 700,000 on election night in PA and now be trailing three days later? That question along with many others have to be answered. Do you want the answer?
