Two senators on the Armed Services Committee lashed out at the classified-document sharing website WikiLeaks on Sunday, hours before a dump of some three million documents including sensitive State Department cables was expected.

"People who do this are low on the food chain as far as I'm concerned," Graham said. "If we can prosecute them, let's try."

PFC Bradley Manning, an intelligence analyst, has been arrested and charged with leaking Defense documents, but the glut of State Dept. information forthcoming suggests a new leak source.

"The people who are leaking these documents need to do a gut check about their patriotism," McCaskill said, adding that the U.S. should go after leakers "with the force of law."

On Sunday morning, the document dump was expected to be hours away. The websites of one of the publications given advance access to the documents, Britain's Guardian newspaper, was down on Sunday morning, seemingly for maintenance or updates.
