Prime Minister Benjamin Netanyahu’s former office director general Eli Groner is joining the Koch business empire. Groner will be the Israel-based managing director of Koch Disruptive Technologies, a subsidiary of Koch Industries that is run by Charles Koch’s son Chase, Jewish Insider reported.

The Koch brothers are well-known American political donors who have spent hundreds of millions of dollars backing conservative causes. While they generally tilt libertarian, they have in the past been accused of donating to anti-Israel idealogues. A 2016 conference hosted by the Charles Koch Institute was criticized in reporting by Tablet and by Eli Lake, a Bloomberg opinion columnist, for featuring Stephen Walt and John Mearsheimer, who coauthored “The Israel Lobby.” Lake noted that the book prompted the Anti-Defamation League to write a response entitled “The Deadliest Lies: The Israel Lobby and the Myth of Jewish Control.”

Chase Koch, 41, is less of a political partisan than his father and uncle, according to Politico, and is also known for making annual visits to Israel, Jewish Insider reported.

Koch Disruptive Technologies was founded in 2017. Its first investment was $150 million in Insightec, an Israeli medical company. Once Groner joins, Israel will be Koch Disruptive Technologies’ first satellite office, according to Jewish Insider, which quoted Groner as calling the development “a vote of confidence in the ingenuity of Israeli entrepreneurs.”
