There's no evidence of Russian/WikiLeaks collusion to influence the U.S election, Nicholas Weaver, a researcher at the International Computer Science Institute at the University of California, Berkeley, tells The Wall Street Journal. But that doesn't mean we won't learn tomorrow of some conspiracy that remains unproven today. "Assange has made it very clear that he's willing to be a useful idiot for any intelligence service," Weaver says, "as long as it furthers his own agenda."
