Who is Sidney Blumenthal?
He is the fiercely loyal and deeply connected former aide to President Bill Clinton and has played many roles – both officially and unofficially – for the Clintons.
But despite his proximity to power, Blumenthal remains relatively unknown outside elite political and media circles.
A treasure trove of Clinton emails, released by the US State Department, revealed new details about the extent to which Blumenthal had unofficially advised Hillary Clinton on several issues during her tenure with the
agency, including acting as a go-between to try to persuade the former secretary of state to help support Tony Blair’s bid to become EU president.
