Google in 2012 sought to help insurgents overthrow Syrian President Bashar Assad, according to State Department emails receiving fresh scrutiny this week.

Messages between former secretary of state Hillary Clinton's team and one of the company's executives detailed the plan for Google to get involved in the region.

"Please keep close hold, but my team is planning to launch a tool ... that will publicly track and map the defections in Syria and which parts of the government they are coming from," Jared Cohen, the head of what was then the company's "Google Ideas" division, wrotein a July 2012 email to several top Clinton officials.
