Monica Lewinsky or "Mega?"

On 20th February 1997, the New York Times reported that an Army Mechanical Engineer and Ashkenazi Jew called David A. Tenenbaum "inadvertently" gave classified military information about armoured vehicles and missile systems to Israeli officials. 

The Washington Post reported that the USA intelligence service had intercepted a conversation in which two Israeli officials had discussed the possibility of obtaining a confidential letter written by Secretary of State Warren Christopher to Palestinian Leader Yasser Arafat. One of the Israelis, identified as "Dov" made a comment that they may get the letter from "Mega." This was known to be the code name for Israel's top agent inside the USA at the time.

  

Israeli agents had been monitoring phone conversation involving Ashkenazi Jew and daughter of a Rabbi, Monica Lewinsky's, at the Watergate Building and they recorded intimate phone sex sessions between her and President Bill Clinton. 

The Ken Starr report confirmed that President Clinton warned Lewinsky that their conversations were being recorded and he ended the affair. Interestingly, at the same time, the FBI called off their hunt for "Mega"
