So I came upon this July 2018 Independent article which quotes social critic Noam Chomsky as saying that Israel interfered in US election(s):
Veteran activist Noam Chomsky has accused Israel of “brazenly” interfering in US electoral politics in a way that vastly outweighs any efforts that may have been carried out by Russia.
However the only example he cites is Netenyahu addressing congress without informing President Obama.
“Israeli intervention in US elections vastly overwhelms anything the Russians may have done, I mean, even to the point where the prime minister of Israel, Netanyahu, goes directly to Congress, without even informing the president, and speaks to Congress, with overwhelming applause, to try to undermine the president’s policies - what happened with Obama and Netanyahu in 2015.”
The Independent are quoting from Chomsky's interview with Democracy Now.
Has there been any interference that backs up this claim?
Only thing I came across was the voting machines, but that appears to just be a conspiracy theory with no backing as far as I can see.
The New York Post also claims that Special Council Robert Mueller has sent investigators to Israel to look into interference, but again does not say how or why anything is suspect.
After further research,
According to The New York Times and The Guardian, which used New York times as a reference, Mueller is investigating an August 2016 meeting between Donald Trump Jr. and "a firm who specialized in data collection and social media persuasion." The firm employed "employed several Israeli former intelligence " to whom it appears large sums of money were transferred after the election
I cannot find if any statement from the probe has been made or the status of this probe/investigation.
So for the sake of this question I will limit "interference" to social media manipulation for the purpose of electing Donald Trump.
