There you again. Spreading Jew hating tropes. Disgusting.
As far as US congress, I'm not aware of even one dual American Israeli citizen.
If there are any, please name them and give credible sources. Please don't bother posting white nationalist / Nazi style sources. I doubt there is even one but if so, even then, it would be very small percentage of Jews in congress.
Do you have a problem with dual American Italian citizens?
There is no law against dual citizens being elected.
I would hope such cases are made public so the voters can decide whether that is relevant.
