In an interview with PBS's Charlie Rose, Guardian Editor-in-Chief Janine Wilson said national security officials raised no concerns before the paper published leaked information about U.S. anti-terror spying techniques.

"We have consulted with the authorities about everything we have published," Wilson said Thursday. She added that the Guardian gave officials the opportunity to voice any objections to what may be published beforehand.

"Did they say, 'we have national security concerns'?" asked Rose. "Actually we haven't. We haven't heard specific national security concerns about any of the material we've released," Wilson replied.

The Guardian was the first paper to publish information about the National Security Agency amassing the phone records of private U.S. citizens.
