In the fall of 2016, Donald Trump Jr. and other key aides to the future president reportedly met in Trump Tower with Joel Zamel, the founder of a company called Wikistrat.

Wikistrat bills itself as a "crowdsourced" geopolitical analysis firm based in Washington, D.C. But interviews with current and former employees and documents reviewed by The Daily Beast tell a different story: that the vast majority of Wikistrat's clients were foreign governments; that Wikistrat is, for all intents and purposes, an Israeli firm; and that the company's work was not just limited to analysis. It also engaged in intelligence collection.

Robert Mueller's office is investigating Wikistrat and Zamel, according to The Wall Street Journal, as the special counsel's probe expands into Middle Eastern governments' attempts to influence American politics.
