Who Is Mega?

IS THERE AN ISRAELI SPY ATthe heart of the U.S. government? In January the National Security Agency decrypted a phone call between the Israeli Embassy in Washington and Tel Aviv talking of ""Mega,'' in a context suggesting Mega is a highly placed spy. Since then, the FBI has been hunting for Mega, even starting surveillance of top National Security Council and State Department officials. The FBI is also revisiting the last U.S./Israel spy scandal, in which navy intelligence analyst Jonathan Pollard was found guilty of passing top-secret documents to Israel. Agents on that case never cracked a bigger mystery: who told Pollard's Israeli handlers which documents to ask for? The FBI is wondering if it was Mega and is irate that word of its hunt has leaked. Some agents suspect the leak was meant to warn Mega to lie low.
