NSA Spied On Soldiers' Personal Calls

The Senate Select Intelligence Committee is looking into allegations from two U.S. military linguists that the government routinely listened in on phone calls of American military and humanitarian aid workers serving overseas.

"These are extremely disturbing allegations," said Committee Chairman Sen. Jay Rockefeller, D-W.Va., in a statement issued Thursday. "We have requested all relevant information from the Bush administration. Any time there is an allegation regarding abuse of the privacy and civil liberties of Americans it is a very serious matter."

ABC News first reported the charges Thursday, citing one current and one former military linguist by name. They are contained in the book "The Shadow Factory," to be published next week.

The linguists said National Security Agency interceptors routinely monitored and recorded the private calls of U.S. military personnel, Red Cross and other humanitarian workers; personal discussions that had entertainment value — pillow talk or phone sex —were shared among intercept operators, they said.
