As a candidate in 2008, Barack Obama pledged to run the most transparent administration" in U.S. history with an "unprecedented level of openness." Seven years into his presidency, Obama's promise rings hollower than ever. A year ago, 38 journalism groups assailed the president's team for "politically driven suppression of the news." Complaints included the inaccessibility of key staffers, delays in interview requests and - most insidiously - the blackballing of reporters who wrote critically of the administration. Photojournalists also objected to the White House's insistence on issuing official images of the president instead of allowing them access. Even before that, The Chronicle had issues with the White House. Our Carla Marinucci was even barred for a time from serving as a pool reporter for presidential visits after she shot video of a spontaneous protest at an April 2011 Obama fundraiser in San Francisco. Most transparent administration in history? Obama has ... prosecuted more leakers under the century-old Espionage Act than all of his predecessors combined. He has continued to defy one of his campaign lines by invoking the state secrets privilege to keep classified information out of court proceedings or to force the dismissal of lawsuits. This administration ... is falling well short of Obama's promise to be the most transparent president in U.S. history.
