Obviously Epstein worked for Israel

‘Calling Jeffrey Epstein a Russian or a Soviet agent is NONSENSE. I’m sure the Israelis are putting it out that he’s a Russian agent.’ Former Israeli Intelligence Officer Ari Ben-Menashe

Obviously.

How can people I greatly respect like Andrew Lownie and Andrew Marr suggest he was principally working for Russia? 

He said years ago that he knew Epstein was Mossad and that Israel blackmails US Presidents (Clinton over Lewinsky before that scandal became public, for example).

Why do the media never mention him or his revelations?

Because the CIA or MI6 would not like it? I'm not sure how it works but would love to.
