Google's plan was highlighted in an email from Jared Cohen, a former State Department adviser who left to run Google Ideas in 2010.
Hillary Clinton’s emails reveal how Google wanted to overthrow Syrian President Bashar al-Assad using a mapping tool.
At a time when America's foreign policy was to topple Assad, the tech giant - whose corporate motto is 'Don't Be Evil' - sought to encourage further defections from the leader's regime and boost the confidence of the opposition.
The plan's details were passed along to Clinton's team by a Google executive Jared Cohen, who was a senior advisor to Clinton until 2010 and is an Adjunct Senior Fellow at the Council on Foreign Relations.
The 34-year-old left his State Department position after being poached by former Google CEO Eric Schmidt to run Google Ideas, now known as Jigsaw.
The revelation comes as Google’s plans to expand Internet access in Cuba were revealed by President Barack Obama on Monday.
Obama, who is on a historic trip to the communist nation, said in an interview with ABC News: ‘One of the things that we’ll be announcing here is that Google has a deal to start setting up more WiFi and broadband access on the island.’
