Go ahead and give us one name of a dual citizen in Congress. Go!

You mean Israeli ones. There are lots of non-Israeli ones.

And probably more undisclosed.

(Ted Cruz had a Canadian dual-citizenship without being aware of it, or so he said when Trump people questioned his eligibility to run for POTUS.)

But that is a straw-man argument.

All Jews (including myself) have an invisible Israeli citizenship.

We can get one the very second we need it.

But there is no benefit to getting that citizenship, if you're a US Citizen and living in the US.

You have no point.
