Republican presidential nominee Donald Trump on Thursday attempted to walk back some of his remarks at a Wednesday morning press briefing during the Democratic National Convention, including his suggestion that Russian intelligence services should look for more than 30,000 deleted emails belonging to former Secretary of State Hillary Clinton and reveal them to the world. "Russia, if you're listening, I hope you'll be able to find the 30,000 emails that are missing," Trump said. "I think you will probably be rewarded mightily by our press."
