When President Obama took office, federal employees who had exposed wrongdoing or were considering doing so had reason for hope. Eight years of the Bush administration's relentless retaliation against whistle-blowers had ended, and Obama spoke encouragingly of transparency and due process.
Since then, the administration has taken some positive steps for whistle-blowers, most notably in (unsuccessfully) advocating legislation to protect them and in loosening the government's grip on public information. However, its treatment of national-security and intelligence whistle-blowers - arguably the ones we need most - has been brutal. It has pursued multiple prosecutions of such whistle-blowers on espionage charges.
