Some former Breitbart writer (I forget which) commented that they saw Ben Shapiro routinely receive phone calls from Mossad telling him how to shape content at Breitbart. I'd be willing to bet that Greenblatt similarly takes directives from the Israeli government. Working at the behest of a foreign government is actually legal if the person registers with the DOJ. Curiously, neither Greenblatt or Shapiro are registered agents. If the FBI actually worked for the American public they'd investigate Greenblatt's connection to the Israeli government.
