Four years ago, on the campaign trail, candidate Barack Obama shared his views on whistleblowers. He said: “Often the best source of information about waste, fraud and abuse in government is a government employee committed to public integrity, willing to speak out. Such acts of courage and patriotism … should be encouraged rather than stifled.”

As president, the reality has been very different. On his watch, six whistleblowers have been charged under the Espionage Act for allegedly mishandling classified information. That is twice as many as all past presidents combined.
