WASHINGTON — As a young lawmaker defining himself as a presidential candidate,Barack Obama visited a center for scholars in August 2007 to give a speech on terrorism. He described a surveillance state run amok and vowed to rein it in. “That means no more illegal wiretapping of American citizens,” he declared. “No more national security letters to spy on citizens who are not suspected of a crime.”
More than six years later, the onetime constitutional lawyer is now the commander in chief presiding over a surveillance state that some of his own advisers think has once again gotten out of control. On Friday, he will give another speech, this time at the Justice Department defending government spying even as he adjusts it to address a wave of public concern over civil liberties.
The journey between those two speeches reflects the transition from the backbench of the United States Senate to the chair behind the Resolute Desk in the Oval Office. Like other presidents before him, the idealistic candidate skeptical of government power found that the tricky trade-offs of national security issues look different to the person charged with using that power to ensure public safety.
