Donald Trump has piled in on the DNC, following damaging revelations of underhand tactics by the supposedly impartial committee against their own candidate Bernie Sanders. So far, Democrats have failed to respond to controversies raised by the leak. “Leaked e-mails of DNC show plans to destroy Bernie Sanders. Mock his heritage and much more. On-line from Wikileakes [sic], really vicious. RIGGED,” tweeted the Republican nominee on Saturday afternoon. “The Wikileaks e-mail release today was so bad to Sanders that it will make it impossible for him to support her, unless he is a fraud!” Trump added in another tweet.
