[I have long detested Kerry. But I've never found any information or indication that he's Jewish. Someone sent me this, but I'm not sure how reliable this is. Jan]

Kerry is an Edomite Jew, as we all know.

John’s paternal grandparents were Austro-Hungarian Jewish immigrants who converted to Catholicism

Mayorkas is an Edomite Jew.

His father was of Cuban Jewish background and his mother a Romanian Jew whose family fled to Cuba.

Avril Haines; Edomite Jew Bitch

Biden’s hooked nose Mama would be so proud of her confessed extortionist.
