Chris McGreal story includes gratuitious reference to donations from 'Jewish billionaires'

We have reported extensively on Guardian journalist Chris McGreal’s malign obsession with Israel, and his tendency on occasion to evoke antisemitic tropes about Jewish power. 
This blog has garnered multiple corrections to substantive errors in stories by McGreal.  In 2011, following complaints by UK Media Watch and others, Guardian editors revised language in a McGreal article suggesting the US was a slave to Israel.  The language was deemed “inconsistent with their editorial standards”.
McGreal’s latest Guardian report (Netanyahu’s alliance with Republicans risks further ire from Obama, April 6) ostensibly deals with the Israeli Prime Minister’s putative alliance with Republicans over opposition to the Iranian nuclear deal, but includes a characteristically gratuitous reference to Jews in the following passage:

Cotton, as the New York Times noted this week, is a major recipient of money from rightwing supporters of Israel. The hardline Emergency Committee for Israel spent nearly $1m to back Cotton’s election. A political action committee run by John Bolton, the hawkish former US ambassador to the UN, gave $825,000 to elect Cotton, its second largest donation of the most recent election. Hundreds of thousands of dollars also came from two Jewish American billionaires who strongly support Netanyahu.

McGreal is presumably referring to two Americans mentioned in a New York Times article linked to in the passage, Sheldon Adelson and Seth Klarman.
It’s important to note that nowhere else in the article is there any mention of anyone else’s religious affiliation, and that clause 12 of the Editor’s Code of Practice includes the following in a section titled ‘Discrimination’.

Details of an individual’s race, colour, religion, sexual orientation, physical or mental illness or disability must be avoided unless genuinely relevant to the story.

So, the question for Guardian editors is this:  How precisely is the religion of Adelson and Klarman relevant to McGreal’s story?
Those concerned about the continuing tendency of radical left and liberal left media outlets to conjure toxic narratives about the injurious impact of “Jewish money” may wish to get answers from McGreal regarding his intent in the passage cited.
