Donald Trump invited Russia to hack Hillary Clinton's emails on Wednesday, asking one of America’s longstanding geopolitical adversaries to find “the 30,000 emails that are missing” from the personal server she used during her time as secretary of state.
“I will tell you this, Russia: If you’re listening, I hope you’re able to find the 30,000 emails that are missing,” the Republican nominee said at a news conference in Florida. “I think you will probably be rewarded mightily by our press.”

But now Trump is demanding that Russia give Crimea 'back' to Ukraine.
Russia has every reason to feel disturbed about Trump.
