The embarrassing leak of thousands of Democratic National Committee emails came from WikiLeaks, but there's some evidence that it originated with Russian hackers. Vladimir Putin has already been injected into the presidential campaign because of Donald Trump's public comments. The Republican presidential nominee has criticized NATO and the sanctions imposed against Russia after it annexed Crimea. He's praised Vladimir Putin. His campaign manager and other advisors have deep ties to the Kremlin — and Trump's son says there's Russian money in the family business. Russian state media are bullish on Trump's campaign, and Trump has said that, if Russia hacked the Democratic National Committee, it should do the same to Hillary Clinton. Is Trump calling for another "re-set with Russia?" Does Putin want Trump to win?
