(CNN) – A day after the whistleblower site WikiLeaks began publishing details from a massive collection of confidential U.S. diplomatic documents, the chorus of criticism from government leaders grew louder Monday. Top U.S. officials were quick to denounce the publication of the leaked documents Sunday. And the U.K.'s foreign office followed suit Monday, saying it condemned any release of classified documents. "They can damage national security, are not in the national interest and, as the U.S. [has] said, may put lives at risk," the office said in a statement.

The full set of documents includes 251,288 cables sent by American diplomats between the end of 1966 and February 2010, WikiLeaks said in a statement announcing the release. Of those, 8,017 originated from the office of the secretary of state, and more than 15,600 are classified as secret, WikiLeaks said.

Today on American Morning, John Roberts talks to James Rubin, former U.S. assistant Secretary of State, about how the information affects national security. Watch to find out why Rubin calls the documents a "broad-based attack on U.S. foreign policy."

Today, Mohamed Osman Mohamud, who was arrested on Friday night for allegedly attempting to detonate a bomb at a Christmas tree lighting ceremony in Oregon, is due in federal court to answer to charges of attempted use of a weapon of mass destruction.

As of a year ago, the 19-year-old naturalized U.S. citizen from Somalia lived with his family in Beaverton, Oregon, across the street from Stephanie Napier.

Stephanie joins John Roberts on American Morning this morning to describe her impression of the Mohamud family.
