President Obama's administration has been arguably more hawkish against national security disclosures (when they don't benefit the administration) than Bush's was[1], and his administration has set up quite a few cases that involved tapping the communications of journalists.
I liked Candidate Obama quite a bit and am fairly disappointed in President Obama's policies. " The Obama administration, which promised during its transition to power that it would enhance “whistle-blower laws to protect federal workers,” has been more prone than any administration in history in trying to silence and prosecute federal workers."[2]
