The Forward (an online publication that covers issues that matter to American Jews) looked at Santos' claims and did an extensive examination of his background. They could find no evidence at all for his claims. As with other facets of his life, he just made **** up. And why would he do that? Well, being Jewish or having a Jewish background is a big asset, especially for a Republican, in a congressional district where over 20% are Jewish, as they are in Nassau County on Long Island and in the part of Queens that comprises NY-03.

So he conveniently lied about that too.

Congressman-elect George Santos’ emotional narrative of having Jewish grandparents who fled Europe during World War II appears to be untrue, like much of the rest of his campaign biography, according to genealogy websites reviewed by the Forward.

Santos, a Long Island Republican, has said that his father was Catholic and his mother was Jewish, and that both faiths “are mine.” The very first line of the “About George” page on his campaign website states: “George’s grandparents fled Jewish persecution in Ukraine, settled in Belgium, and again fled persecution during WWII.”

But the website myheritage.com lists Santos’ maternal grandparents as having both been born in Brazil before the Nazis rose to power — his grandfather, Paulo Horta Devolder, in 1918, and his grandmother, Rosalina Caruso Horta Devolder, in Rio, in 1927. An online obituary for Santos’ mother, Fatima Aziza Caruso Horta Devolder, who died in 2016, says she was born in Niterói, a suburb of Rio de Janeiro, on Dec. 22, 1962, to Paul and Rosalina Devolder.

Fatima’s own Facebook page, which has photos of her with Santos and tags his page, has no mentions of the words “Jew” or “Jewish,” nor the terms Yom Kippur, Shabbat or Israel in English or Portuguese. But four of the seven pages she “liked” were for Catholic groups, and another was for a Brazilian priest and singer.

Naturally enough, Santos' lawyer released a statement dismissing the report as a “shotgun blast of attacks” and “defamatory allegations.” But Santos' own campaign has remained mute when pressed for comment by The Forward, The Jewish Telegraph, and others. Even Matt Brooks, head of the Republican Jewish Coalition has called the allegations "troubling", but they haven't heard back from Santos either, nor are they likely to. I mean, why would they? Santos attended the RJC’s convention in Las Vegas, billed as one of two freshmen Jewish Republicans. (The other is Ohio’s Max Miller.) To find out now that one of them is a liar would be a tad embarrassing, wouldn't it?
