WASHINGTON (Reuters) - President Barack Obama's administration is likely to open a criminal investigation into the leaking of highly classified documents that revealed the secret surveillance of Americans' telephone and email traffic, U.S. officials said on Friday.

The law enforcement and security officials, who were not authorized to speak publicly, said the agencies that normally conduct such investigations, including the FBI and Justice Department, were expecting a probe into the leaks to a British and an American newspaper.
