U.S. officials warn of new WikiLeaks release

WASHINGTON Though WikiLeaks has not revealed specifics about the U.S. documents it plans to release, the material is thought to include private, candid assessments of foreign leaders and governments.

State Department spokesman P.J. Crowley has warned the release of the documents would endanger lives and harm national security, but foreign policy expert Michael O'Hanlon of the Brookings Institution is skeptical.

Crowley called the release "irresponsible."
