It’s the morning of April 25, 2016. At a hotel in London, a Maltese professor meets with a young foreign policy adviser to the Trump campaign. The two have been in touch over the past few weeks; the professor has been helping the young man connect with Russian officials. Now, over breakfast, the professor lets him in on a secret. On a recent trip to Moscow, high-level government officials told him that the Russians have “dirt” on Trump’s opponent. What was the “dirt” in question? “Emails,” he says. They have “have thousands of emails.”
